Acid catalyzed formation reaction mechanism : Step-1 : An acid or base reaction, there is only a weak nucleophile we need to active the carbonyl group by protonating on O. Step2 : The nucleophilic O in the alcohol attacks the electrophilic C in the C=O, braking the pi-bond and giving the electrons to the positive O.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
