Do we need to know for the current AQA spec how sigma/pi bonds work? And in more complicated questions if both compounds have a spare pair of electrons how do we know which compound donates their pair and which one receives it?
+Ashleigh Knowles Not particularly, just have to remember the general reactions really. They all follow some kind of pattern e.g. acid + carbonate will produce salt, carbon dioxide and water. Keep practicing. Exam papers and you will see that many of them you will become familiar with the general products.
I’m sure you probably do not need the explanation now, but I’ll say anyway. Essentially the structure of a benzene ring isn’t what most think with every other bond on the carbon chain to be a double bond. That is not right, due to p orbitals that aren’t being used because they are all carbon-carbon single bonds, every carbon atom has a p orbital that sits above and below that carbon atom, these overlap with the p orbitals from other carbon atoms, which creates a pi system. So essentially it’s 12 sigma bonds because kekule’s model is incorrect, there are no carbon-carbon double bonds.
trying to understand Schrodingers equation (I don't think I even spelt his name right). I just don't understand the way he notates his orbitals need help
Thank you so much . You have helped me a lot .

Do you need to know sigma and pi bonds for AQA? Thanks
no you don't
can u please add video of gaseous state
As in, how can you work out, from the reactants, what the products will be? is there a way? I'm not sure if they're is that's why I asked :) thank you

+Allery Chemistry thank you I😆
Life saving 😭😭
can we have four covalent bonds between corbon atoms
Waqas Waqar yes such as CH4
Carbon always form 4 bonds
Does carbon monoxide have 4 bonds
Thank you, this was very helpful!
could you please add videos of hybridization
Which exam board do you do?
Allery Chemistry as level
Which exam board are you studying though?
Allery Chemistry as level
He means are you doing OCR, AQA or what?
Is there any video we’re he explains polarastion and iso electronic ions ?
Is the double bond in the oxygen a pi bond?
Also do you do private tutoring?
p orbital dumbell shape? and a sigma bond??
Please could you do a video on how to predict products of a reaction? Thank you :)
+Ashleigh Knowles What do you mean predict products of a reaction?
thank you
😀😄
Where do you get the positive charge in NH4+
Ammonia NH3 has no charge. When add H+ ion you get NH4+ as overall charge is now positive
Could anyone please explain why exactly benzene has 12 sigma bonds?

thank you
It can't seen properly
But pi bonds have 4 electrons, 1 pair in the sigma bond and 2 electrons in each cloud
nidheneeeee urgh
Legend !
