A Level Chemistry Revision "Oxidation of Primary Alcohols"

You can find all my A Level Chemistry videos fully indexed at www.freesciencelessons.co.uk/...
In this video, we look at the oxidation of primary alcohols. First we look at what is meant by an oxidising agent. We then look at how we can oxidise a primary alcohol to an aldehyde. Then we explore how to continue the oxidation to produce a carboxylic acid and how to maximise the chances that this reaction goes to completion.
This video is aimed at the UK A Level Chemistry specifications. Students studying International A Level Chemistry will need to check their specification.

This is what I need, rather than some lengthy, unclear, winding explanation video. It's clear, short yet has everything you need, perfect for a revision. (I'm doing A2 and need to go back to learn some as stuff that I forget). Thank you so much for making these videos!

Did you pass?

[@glitchedout8079]

Thank you sir, you're a lifesaver

[@user-eb4vx2iy2w]

Thank you sir. you are genuine lifesaver

After oxidising aldehyde, why we don't make a water molecule?

[@OmniversalInsect]

I will use these when I do a level chemistry next year ty

[@rainb1750]

1:50 is the -OH function not suppose to be attached to near the c-c bond for (ethanol)
if so why

[@Freesciencelessons]

Can you explain what you mean please? The OH group is attached to one of the two carbon atoms in the ethanol.

Then what are the specific oxidizing agent take place between aldehyde and carboxilic acid, is it also K2Cr2O7?

[@Freesciencelessons]

Yes that's correct.

[@BHAGYASHRI_k]

And sir and why tertiary alcohol is do not react ??

[@Freesciencelessons]

In oxidation of alcohols, a hydrogen atom is removed from the same carbon as the hydroxyl group. In a tertiary alcohol, this carbon atom does not have a hydrogen (it has an alkyl group such as methyl). So it cannot undergo oxidation.

[@Axxturel1288]

At the end when we separate the reaction mix how come the alcohol isn’t still mixed with the carboxylic acid even with distillation since alcohols also have hydrogen bonding?

[@Freesciencelessons]

We may need several rounds of fractional distillation to effectively separate the carboxylic acid from any unreacted alcohol.

I miss the blue background😪

It's back in the most recent videos.
