GCSE Chemistry - Esters #59

This video covers:
- What esters are
- How they're made from carboxylic acids and alcohols
- Their properties

Exam board specific info:
AQA - Everything is relevant to your course! You only need to know the example of ethyl ethanoate.
IGCSE Edexcel - Separate/triple science and higher tier only
Edexcel - Not in course, but useful for understanding condensation polymers
OCR 21st Century - Not in course, but useful for understanding condensation polymers
OCR Gateway - Not in course, but useful for understanding condensation polymers

Amadeus, you are a living legend. Truly, I passed my recent Chemistry exam with 97.3% because of these videos. Keep up the great work...

[eviejackson]

These videos are saving my gcse the night before my exam. Thank you so much 🙏😭

I keep forgetting chemistry as my brain rejects it and I keep failing them but listening to your videos really helped me to keep these information in my head, I really really love your videos and I will support you as long as I can <3

[ADerpyHeap]

These videos are literally saving my science grade, thank you!

Your every video I saw are less than 5 minutes, but teach more than a 90 minute chemistry sessions

What I learned from the video:
*Esters often have a pleasant smell, meaning they are sweet or fruity.
*They are volatile, meaning that esters can evaporate easily.
*Uses: Used in perfumes and food flavorings.
*Carboxylic acid + Alcohol Ester + Water (A concentrated sulfuric acid catalyst is used)
*Moreover, when carboxylic acid and alcohol combine or react together, the carboxylic acid loses its -OH group, and the alcohol loses the hydrogen atom from the -OH group. Together, these three atoms form a water molecule (byproduct)
Eg. Propanoic acid + Propanol Propyl Propanoate + Water (Concentrated H2SO4 is used)
*Conclusion: Esters are another homologous series with a -COO functional group, which is called the 'ester group' or 'ester link.'

Yeah, to be honest I used to spend many hours to study like physics and chemistry but when I watch your videos I just truly understand

[localsleepdeprivedmonkey]

You guys are reallyy helping me with school!! I always come to you guys whether I understand a topic or not, so my recommended page is filled with u!!

[Maen]

I just watched 3 videos about organic chemistry which were alcohol, carboxylic acid and esters. I understood everything that I was confused in for a whole week, that took me 9 minutes and 15 second to master this lesson. I would like to call you the master of chemistry

[mprseez]

This is very useful, Thank you.

[laibanauman]

Thankyou so much!!
Your videos are literally gem
I’ll be appearing for GCSE in May/June 23 and I always use your videos
Recommend your channel to every science student
Hats off 🫶🏻

[savinezongo]

Thank yoou! this will help my alot for my test :)

[greenred]

Thanks for the helpful video!
I would really appreciate it if you could make a video on how to name and draw esters.
Thank you 👍

[linaamin]

Man one of my friends recommended this and thank you for helping 😭✨

[irqmcxh]

You are much better teacher than my school teachers.

Thanks for kept save us
Over generation 😂❤

[aaravsethi]

What a helpful video and so captivating

[eviyulistia]

Hi, I just wondering, since the carboxylic acid is more "acid" they will release their hydrogen from -COOH functional group. So the acid will loose the Hydrogen and the alcohol will release the -OH, isn't it?

we still have 200k subs more to go. we gotta make him reach 1million
