In terms of physical properties of alkanes, where does that appear on the spec and is it necessary to know them? I haven't come across any questions on solubility or polarity for example
The big one is boiling point. Not specific to alkanes but you need to know about larger Molecules having more van der Waals forces. This fits into the Bonding topic and to Fractional Distillation. Solubility can come up in a few places. Most commonly in chemical analysis and spectroscopy, put simply from the point of view of alkanes being non-polar and therefore dissolving non Polar things and being insoluble in water. It can come in more indirectly with ideas about why they are not susceptible to attack by nucleophiles or electrophiles as well
You're right. The temperature for catalytic cracking that I wrote should have been in kelvin! Great spot! It's about 500 degrees Celsius (it's fine to generalise to an approximate temp as different refineries vary slightly)
Correct... and not just alkanes. For any molecule at all the Covalent bonds are always much stronger than the intermolecular forces. Typically at least 10 x stronger
It does get tricky with cylic Compounds. Good news is you are more likely to be asked to draw them as functional group Isomers of alkenes than you are to name them
Hi, yes, this video will be suitable for any exam board. I teach AQA so I always make sure it covers everything needed for AQA. All exam boards are at least 95% the same though. The main differences between them is not the content they include, but rather how they structure the course, what topics are on each exam and the question style
Perhaps the best part of this channel is that you reply to every comment. That shows you actually do care for your audience. Great video as always
Thank you! I do really appreciate all the feedback and the encouragement. It helps keep me going!
Noticed the same , and that is kind of him . And commendable if I may add ❤.
Bro these videos are amazing, you explain everything so well. Im going to make sure to share your videos to the rest of my class ! thank you !!!!
Your kind words are much appreciated, thank-you!
These videos are the best I’m so grateful thank you so much
Sir you are amazing, thank you so much for your videos. I have an exam tomorrow and this video sums it up beautifully!!!
That's lovely to hear! I'm glad it's useful 😊

Thank you so much for saving my life
I'm really glad you found it useful!
Very helpful thank you ❤🎉
I'm really glad you've found it useful 👍
Hi Sir, thanks for the video, do you have any videos on chlorination and free radical equation solving?
You're very welcome!
Yes, here is an explanation videos

And here is an exam question walkthrough ua-cam.com/video/hHIcm1QlqA0/v-deo.html
Subscribed! Thanks.
😊👍
Thank you so much😀
You're very welcome! Glad these videos are useful 😃
Do we need to know about vacuum distillation for AQA?
Good question, no you do not
Great Video!!
Just got confused by temperature conditions such as At 29:45 is the unit used degree celcius or Kelvin ?
Thank You

@@chemistrytutor Thank You !! Absolutely goated videos !!
@@zhar9177 😀👍
Thank you
You're welcome 😊
So good
Thank you 😊
So alkanes have weak intermolecular forces and strong intramolecular forces?
Correct... and not just alkanes. For any molecule at all the Covalent bonds are always much stronger than the intermolecular forces. Typically at least 10 x stronger
The cyclo nomenclature was a little bit buzzy for me
It does get tricky with cylic Compounds. Good news is you are more likely to be asked to draw them as functional group Isomers of alkenes than you are to name them
@@chemistrytutor oh okay. Thanks
That aside, I'm sharing this
Many thanks 😊
Glad it's useful
Is this also for CAIEs As level??
