I’m an experienced Science teacher in the UK. I’ve taught A Level Chemistry, GCSE Physics and GCSE Chemistry for 18 years. I have a joint honours degrees in Chemistry and Mathematics.
Main focus on AQA A Level specification and BTEC Applied Science but is also useful for other specifications.
At present, videos are designed as full lessons for you to work along and complete tasks as you learn. In the future, as the channel grows, I will be uploading revision videos and techniques.
Thanks for your support, I appreciate it!

BTEC Applied Science - Unit 5 Chemistry - June 2017 Exam Paper
Hi Bryson I hope you are doing well. I have been watching your UA-cam videos since at the start of sixth form college. I'm still subscribed to this channel. I did BTEC Applied Science from 2020 to 2022. I want to say thank you so much for your help because without the existence of this channel, I wouldn't have no chemistry knowledge. Currently, I am in my third of university studying forensic science and after this I will be progressing to my fourth year!
I’m so confused by this
For the hydration of ethene, are u not meant to understand the mechanism?
The spec isn’t very clear on this but it isn’t listed. You definitely need it for A-Level Chemistry
hello sir can u explain me why the melting point increases as the atomic number increases in group 7
All group 7 elements are diatomic and non-polar molecules. As such, they only have van der Waal’s forces of attraction between molecules. As you go down the group, the molecules become bigger and have more electrons. This means the van der Waals forces are stronger and more energy is needed to overcome these forces…this results in a higher boiling point
this video is so helpful I never fully understood this part of the content but u have explained it so well thank you sososoosos much
where can i find a video about metallic bonding
Haven’t made one…yet
@ not yet
@@BrysonChemistry so did u cover all A2 for chemistry?
Ahh yes I get hybridization I thought it wasmt p orbitals I thought the number of sp2 represented the actual electrons only not the orbitals
best video i could find on the topic
This is really helpful ❤
7:50 how come its methyl and not ethyl? isnt ethyl the branch CH2-CH3
You have to find the longest chain first…this leaves the methyl a side group and not ethyl as the ethyl makes up part of the chain
I got D using your videos last year. This year with having limited time I am really behind. I am using your videos and I know they will help. Thank you Bryson. I recommend Bryson videos cuz they help a lot as he makes his videos following the spec. I recommend to anyone doing applied science Bryson and betc applied science help by dave.
9:05 i got 1,2,3 tri-methyl-pentane....
No such thing as “1 methyl” because if it’s on the first C then it’s just another C in the chain so the chain is one longer
hi, ive got my exams in January coming up, i was wondering whether or not we need to learn the electrochemical series this year?
I would be very surprised if they expected you to know it…it’s more about knowing what it is and how you can use it
Thank you so much for this explanation God bless you ❤
Why is experimental value higher than expected? Is it because there is higher than expected energy released from the formation of ionic bonds?
No, it’s because the experimental value will include any covalent character if it’s present
No, it’s because the experimental value will include any covalent character if it’s present
Can this apply to CTEC science
What is CTEC?
BTEC yes
@@danielogwezi358 yes, this series of videos is for BTEC Applied Science
@@BrysonChemistry it’s OCR exam board of BTEC. I think it’s the same thing but different exam board
@ ah ok…well chemistry is chemistry so if this topic in on there then yes it’s relevant
Faze_Yaze
Thank you so much sir, I was struggling to find out what I needed/ didnt need to know.
liked ur voice subscribed thank ur genetics
Thanks for the sub!
4:13 shouldnt it be 3 chloromethyl pentane as it still follows IUPAC?
Yes, that would work if you were naming it as an alkane with a side chain containing Cl. It’s more common to name the molecule by its functional group though, in this case a halogenoalkane…this means it has to be in the longest chain
Very educative ❤
Thanks this will help me understand the trend in periodic table better ❤❤❤
Pleased it was useful
How do you know that the long line is a methyl? 4:50
The line represents a bond. If there’s no atom shown at the end of the bond then you know it’s a C atom…you also know that C has to have 4 bonds and in skeletal we don’t show C-H bonds…so the C at the end of the line must have 3 H’s bonds to it…so it’s a CH3 group which is a methyl
Great explanation Sir!!
Glad you liked it
I am behind on my studies this year. Last year You helped me a lot and ended up getting a distinction. This year, I can not wait to watch your usefull videos again.❤
Very well explained
Glad it was helpful!
Great video🙏
Thank you 🙌
really amazing teacher who deserves more recognition! please keep posting your videos have really made a level chemistry feel easier and more accessible for me :)
Thanks for the helpful video! Why do ionic compounds with covalent character have a lower melting point than expected please?
This is an awkward one to explain easily…since large lattice enthalpy should mean higher melting point right? But it’s not the case when it comes to large amount of covalent character…I’ll try to explain in the most simple way. If it’s 100% ionic then all ionic bonds need to be broken in order for ions to move freely. If it has covalent character then all bonds don’t have to be broken for the ions to move freely, meaning the melting point is lower despite the fact that the lattice enthalpy is more exothermic. Lattice enthalpy isn’t the same as melting, lattice enthalpy is from (g) state and involves all bonds to fully separate ions, not just enough energy to allow them to move. Hope this helps??
@@BrysonChemistry Ahh okay, yes this is very helpful. Thanks!
12:03 you forgot to add the other bromine in the skeletal formula, nonetheless it was a good video, thank you!
Good spot! Yes you’re right. Thanks for watching
thank you for these videos!
Thanks…I need to add some more and finish unit 1…good luck with the exams
@@BrysonChemistry thank you! 😁
5.02>> do they not loose 3 electrons as they have extra 3 to become stable aluminium atom
No, the positive aluminium ions gain electrons to become aluminium atoms
but -1 is bigger than -2. how come -2 is has a stronger attraction when -2 is smaller than -1?
Smaller in size and bigger in charge means the charge is much more concentrated and this makes it more attractive
-1 and and -2 in the sense the atom gains 1 or 2 electrons that is what - stands for as there is more number of electrons than proton after gaining electrons
Yes
"And this is james bond" that was so unfunny that it actually made me laugh LOL 😭 keep up the vids !
How come the product for the Al2O3 + 6NaOH + 3H2O reaction appear as 2Na3Al(OH)6 and not 2Na3Al(OH)7? I was thinking the water molecules would make an extra OH ion but apparently not.
My equation is correct…I’m pretty sure you won’t need to memorise the equation, it’s important that you know amphoteric means it will react with acids and bases
in the last example, why didn't we use the brackets in the structural formula?
You don’t have to use brackets if you don’t want to, brackets just make it easier to visualise
@@BrysonChemistry Thanks I really appreciate your work
i dont get how i should be making my 2 routes. because i got 130 instead of -130. can you explain how we should know where we have our start and end and how we predict that 2 routes
hi, where can i find the rest of learning aim 2 content? thank you
I’ll have to get back on it!
hello, when are the updated unit 1 videos coming out ? Thanks
I’ll have to get back on it!
Name. Damanpreet SINGH class. 6A
I was genuinely so confused about naming alkenes before i watched. Now that i’ve watched i finally feel like i understood. Your video was the only one that i could understand. You deserve a bigger audience. Thank you againnn!!!
Omg. You’re literally a saviour
thank u! very helpful
this is really useful thank you!
Please consider white text on black
The white on dark blue works well doesn’t it?
thank youu
You're welcome!
Free radical addition showed up as a 6 marker in the unit 5 paper today instead of free radical substitution
I’ve not seen the paper yet!
Thank you so much for these, it is very difficult to find good revision videos for applied science and yours are perfect!
I’m going to make more to cover full unit 1 and hope to have them in place before May exam
