I watch many maths and science tutorials on youtube and never post comments but having watched so many of your videos I thought I should post a thank you for the excellent videos you are producing. In my opinion your chemistry videos are the best at A level science on youtube and I highly recommend them to anyone studying chemistry at school or as an independent learner. I have a degree in Natural Sciences majoring in physics so can speak from experience on the excellence of your teaching. So thank you!
@@AlleryChemistry You're welcome and I'm glad it means a lot to you because you are worthy of such high praise! It must have taken you hours to produce these slides, and very clever choice of design they are too - they really aid the viewer on learning the key points for their syllabus. And your accompanying narrative clarifies and reinforces each new idea. Your early white board videos were already my favourite choice at A level. Keep up the good work! It's much appreciated by me and I'm sure by many current and future students yet to follow.
Dear Mr Allery, I don't usually comment on videos, however, you are genuinely a legend and put so much effort to create incredibly useful videos, so I couldn't help but express my gratitude. Thank you so much!
These videos have gotten me through my chemistry A level. I just want to thank you for your amazing work as it truly has been so useful for my learning through these 2 years. It was 50% these videos and 50% my work that have gotten me my good grades so you deserve the credit. Thank you.
THANK YOUUUUUUUU you're the best banged out this whole topic in a day I'll be binging all these over half term too I love them so much. I hope you have an amazing life you are a saviour
Hi Mr Harris, thanks for your video(s). These videos are really helpful! Just a little correction though, at 1:19:13, the repeat unit for Terylene should have a an O at the end on the right after C2H4. Once again, really appreciate you and your videos!
I think you missed out a part. Section 18B - 9) IV Halogenoalkanes. I dont really know if im missing it, but i cant find it on the video. Thought id let you know. Would be appreciated if you could let me know back
does it matter where on the benzene ring groups are attached ? like isomers and stuff ?like if there are multiple substitutions, would they just be next to each other ? or why do they join in a specific way in 2,4,6-tribromophenol? i'm awful at organic chem
Hi, You mentioned that benzene has a high electron density, but I thought it has a low electron density as the 6 delocalised electrons are spread out over the 6 carbon atoms and so it is not able to form a dipole on the Br2, hence making Benzene a more stable molecule. Is this correct? Thank you very much your videos are so useful!

Totally agree!
it should actually be illegal making us memorise all of these reactions for just 3 topics out of 19 for just 1 a level....
honestly
Just a memory game

‘You might have done hydration reactions already’ *me in lockdown knowing we’ve missed half the CPACS*
THANK YOUUUUUUUU you're the best banged out this whole topic in a day I'll be binging all these over half term too I love them so much. I hope you have an amazing life you are a saviour
back here, thanks so much, disgusting grueling topic but you made it bearable, thank you
wow 2hrs thank u
You're welcome! Longest video I have ever done but it is a huge topic!

Noticed this too..thank god I'm not going insane. Also the O attached and end of C=O shoukd be removed I believe
A big thank you for the videos, personally i dont need a text book. God bless you.
44:56 YO YO MR WHITE ITS TIME TO COOK
Awesome!!!! you really saved me!! thanks a lot!
You are welcome!
1:56:39 shouldn't that be divide the molecular formula mass by the empirical formula mass?
I want to personally thank you for this amazing video. Got me through this topic!
You're so welcome!
Allery da 🐐 no 🧢
Have you got any tips on how to remember all this,there is so much to remember
I think you missed out a part. Section 18B - 9) IV Halogenoalkanes. I dont really know if im missing it, but i cant find it on the video. Thought id let you know. Would be appreciated if you could let me know back

I’m so cooked 😂😂😭

where's formation of azo dyes?
This video was made in 2020, Im also confused. Maybe it was newly added.
Hi,

Is this correct? Thank you very much your videos are so useful!
Is has the same number of electron they just delocalize above and below the ring
45:00 - 1:03:00
1:17:15 how do we know 2 water are produced and not just the one?
i think its supposed to be one
You are a legend. Thank you so much!
U should do CIE also
He did :)
Is the bond length of benzene 139 pm or 0.139 nm
I think those are the same, pm is x10^3 of nm.
thank you for all your effort!! :))
No worries!
