The mechanism for the given reaction is to be written. Concept introduction: The vicinal diols , on reaction with ketone in the presence of acidic condition, forms an acetal. The ketone protonates and forms hemiacetal by a nucleophilic attack of hydroxyl group of vicinal diol. The hemiacetal on protonation followed by nucleophilic attack of second hydroxyl group of vicinal diol forms acetal.

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
