Making esters - Part 1 | Chemistry Tutorial

[@euansimpson5010]

This is amazing I hope you do more of these because you explain the reactions so well thankyou so much

[@TheAnimatedTeacher]

Excellent and clear explanation of each step. Thank you! I will be using this with my year 12 chemistry class.

Hi there! Hi there! Hi there! Hey there! Have you heard about sin? Basically, it is anything that is wrong that we do to upset God. Sin upsets God because He is Holy. Just like this( Imagine if you saw someone being robbed!) God does not like sin, and Heaven is His God's home. So imagine you are sinning and trying to enter into God's house! What happens is, you OWN'T end up in God's House! Basically, you end up in Satan's, the creature who is decieving souls into going to his house, hell, which will be his permanent residence in a few years, where he wants to take millions of souls including yours! There is no second chance when you gte into hell. It is jail, but aint no bail". And that's why Jesus died. He died in our place, that we might just have a chance at life if we believed in Him. Repent of your sins and believe in Him!.

4 minutes in and this is sooooo much fun!🎉🎉🎉 thank you for this video!

[@sakai9848]

This is a great video! Very well explained!

[@LeboMaite]

Why do esters with higher molecular masses not have strong odours

[@ستارهسهیل-ذ7ن]

You explained in details, Thanks! It was perfect explanation

[@joebine6644]

It was enjoyed and knowledgeable!!!❤ awesome video

[@prachisarkate6169]

If we want aolid form of product then what to do

[@bluemacaroons]

Thank you! This made my chemistry hw make more sense

[@willyhsu4341]

what could be a possible resaon that my ethyl acetate isn't splitting with water during isolation?

[@Al-Hussainy]

Very interesting, thank you for sharing this

[@roslailiyuhanisramli2753]

What concentration is the sulphuric acid used?

[@dalelane1948]

haha, I remember this lab from y first degree at Curtin, same lab 20yrs later.

[@hkharis07]

why did nt you add any water immiscible organic solvent like diethy ether or any to extract ester?

[@mattflores8911]

Would magnesium sulfate be a good drying agent as well?

[@FerociousPancake888]

Yes

[@PaynePro]

Thanks 🙏🏾

[@shescynical946]

thank you so much for this! it helped me so much.

[@shahamshooraj2794]

very good

[@injectormajor]

thank you! thats useful

[@curtinuniversity]

Glad it was helpful!

[@johnblacksuperchemist2556]

QUESTION.........I know you can shift the equilibrium by adding an abundance of one of the reactants. Usually that is the alcohol. Why did you choose acetic acid as the abundant reactant????????????? Was there a reason or was it just an arbitrary choice??????????

[@yaserbatal6474]

The acid works as a catalyst as well

[@bigdoggy3031]

Isnt there already water in the mixture after reflux? Why do have to add water? 6:34

[@bluemacaroons]

I think it dissolves the other substances which are water soluble so they separate from the ester

[@yaserbatal6474]

Ester partially dissolve in acidic solutions. Adding water breaks this solution into its components

[@leoking7290]

How can we separate unreacted alcohol from ester. Specially in case of isopentyl alcohol and isopentyl acetate.

[@birch8109]

Distillation is used

[@leoking7290]

@@birch8109 I have tried Distillation but end product is not getting completely free from starting material. Due to small difference in boiling point and there ability to make azeotrope it's not happening. Can you put some insight of type of distillation or conditions which can solve this problem?

[@Bismillah-fo7ru]

I think that's why they have used the alcohol as the limiting reagent with excess carboxylic acid, since the carboxylic acids (especially short chain one's) can be made into a soluble salt by adding carbonate.

[@LemonAndMarm]

Thank you!!

[@Nanya-MF]

Why is the mixture boiled under reflux

[@birch8109]

So that the vessel can be unsealed so there's no build up of pressure but at the same time no vapours escape because they all get condensed and drip back down. Also heating it makes the reaction proceed faster.

GREAT VIDEO

[@user-kr3ct9oh4y]

Thnks a lot, very helpful video!!
