Glad it was helpful!

3 hours before exam, I'll let you know if i get an A*. thanks alot mate.

[@MaChemGuy]

iBsProds Good luck!!!

Just got back from the exam center and I'm glad to tell you that I'm losing 3-4 marks max in paper 4. Your organic chemistry videos were extremely helpful. I will be sure to check out your As/A level videos!

[@MaChemGuy]

Fingers crossed! Thanks for letting me know

Hi, in base hydrolysis why is it only the carboxylic acid that forms a salt and not the alcohol as well? Many thanks :))

[@MaChemGuy]

3 D Salts form when H+ of an acid is replaced by a metal ion. Alcohols don’t have an H+

[@indiadickinson9743]

So it's just because the NH2 group is a base and accepts the proton in acid hydrolysis? Thank you!

@@MaChemGuy there was this question on a past paper with a benzene which had an alcohol and carboxylic acid group and excess NaOH resulted in O-Na+ in both the OH of the alcohol and the OH of the carboxylic acid . Is that because phenols are also acidic ?

@@fatmabatmaz2 yup

What makes the ester bonds break?

What would the dicarboxylate salt be called?

unfortunately no mechanisms for the reactions, only educts and products
