📝 AQA specification:

✅ Specification check:
- The structure of esters
- Carboxylic acids and alcohols react, in the presence of an acid catalyst, to give esters
- Esters can be hydrolysed in acid or alkaline conditions to form alcohols and carboxylic acids or salts of carboxylic acids
- Common uses of esters (e.g., in solvents, plasticisers, perfumes, and food flavourings)

You're honestly a savour, my paper 2 is tomorrow and I'm speeding through your videos. I've never understood this before and struggled with remembering all the required mechanisms. I actually feel like I have a chance to pass now. Thank you

[ShaynaYasmeen-ep]

Sir as there is time left for the exam please make more videos like this. I just love how you style your videos and your explanation is amazing. Please make videos about organic chemistry A levels such as hard subjects like amines in A2, condensation polymers. You can even focus on the required practicals and what we need to know for each if u want. I just want to thank you SO MUCH for your hardwork and the amount of time you put in this videos. I am for sure going to recommend you to other people. Thank U!!!

[marijabrauceja]

I love this channel! Thank you so much for your work!

[peachtea]

thank you so much for these videos! ive been going through all of your videos during this last week of revison for paper 1 :) if you can, please make more videos on electrochemistry because i never get marks on any of those questions, , again ty!!!!

[AelHydrangea]

Thank you so much for your videos, they're so helpful! I hope you gain more subscribers because you really deserve it, thank you so much

[arya]

thanks u actual legend appreciate u! last exam today hopefully goes well :)

[ada]

Thanks for the video I really like what you've done with your channel.

[gaanavmanyam]

Could make videos on graph skills and interpretation, please?

[alevels]

Thank you so much this was super useful

[studyingforreal]

This video is amazing! Just a bit of criticism though, you forgot to mention that carboxylate salts are used in soap, which is something you need to know (its in the spec)!!!

Hello! At 27:31, for question 4, can we say "Carboxylic acids and alcohols contain hydrogen bonding, whereas esters contain dipole-dipole forces. Hydrogen bonds are stronger than dipole-dipole forces. Therefore, it requires more energy to break the hydrogen bonds. Hence, esters have lower b.p" ?. Great video!

[ahmadqayum]

Hi. Great video as always. Could you do an AQA walkthrough on an esters question if possible please? Thanks :)

[xdyfiex]

could you do more exam walkthroughs please? you explain very well

[lamiyakhokon]

i thought because acid catalyst you need to make esters is conc h2so4 hence the hydrolysis process should also need conc h2so4. am i wrong?

[alaziziomar_]

make a video on polymerisation please!!

[umayyahosman]

During esterification, isnt it that the OH comes from the carboxylic acid and just the H from the alcohol?
Thank you

[jameslee]

could you do one video explaining transition metal? struggling to understand it.

[unojzel]

How come you didn’t include the reaction between acid anhydrides and alcohols to form esters ?
