Ch3COOCH2CH3 + HCL = ?

I am doing the question in title and the reaction is:


Ch3COOCH2CH3 the arrow with HCL(aq) on top and heat at the bottom of the arrow.


See I think it is:

EDIT - CH3COOH + CH3CH2OH

Thanks all :smile:

That looks right.

EDIT: wait... no it isn't. The acid acts as a catalyst. You get a carboxylic acid and an alcohol.

Thank you :biggrin:

Can I just ask you, that one of the mark schemes albeit a specimen paper (mark scheme) says that the answer is CH3COOH + CH3CH2OH.

Is the above therefore wrong.

Just saw your edit :smile:

Does that mean the answer is: CH3COOH +CH3CH2OH

CH3COCL + CH3CH2OH

Is this correct?

Two marks schemes say diffferent things, but I believe it to be that.

Thanks.


This is acid hydrolysis of an ester, so you get an alcohol and a carboxylic acid.

Of course yes, I see.

Would it be this then, CH3COOH +CH3CH2OH

Thanks :smile:

CH3COOCH2CH3 is slightly ambiguous. Most people will understand it as ethyl acetate, but it can be also methyl propionate.

Does the reaction take place in water? Most likely it does, and if so, hydrolysis is the most obvious answer.

And your idea about acyl chloride is wrong for an obvious reason: acyl chloride is not something that would survive in the presence of water or alcohol.

Yes. The HCL being above the arrow and the (aq) state symbol are important here. The HCL above the arrow tells you it's a catalyst therefore does not change after the reaction and the (aq) tells you that there is (as far as A-level goes) water.

Sorry for late replies, trying to multitask :P

Oh right yeah :smile: Thanks for clearing that up that makes sense, changed the OP now :smile:

Ah yes that makes sense. No problem, thank you for helping me.
