hydrolysis question

[Ice-cream]

hey does any1 know that out of acyl chloride, amide, acyl anhydride, ketone and ester...which one won't undergo hydrolysis? do carboxylic acids and their derivatives always undergo hydrolysis?

 

thanx

Ketones won't under go hydrolysis. You're right that all carboxylic acid derivatives can undergo hydrolysis. This is because carboxylic acid derivatives are synthesized through a dehydration reaction with another compound. The reverse reaction (hydrolysis) converts the derivative back into a carboxylic acid. Carboxylic acids won't undergo hydrolysis because if you hydrolyze a carboxylic acid, you get the same carboxylic acid.
