(a) Interpretation: The mechanism for the given reactions is to be proposed. Concept introduction: A nucleophilic addition reaction involves a polar π bond which has an atom that is relatively electron-poor (i.e electrophile), so it tends to undergo the addition of a nucleophile, which is electron-rich. The most common polar π bond that participates in nucleophilic addition reactions is the one in the carbonyl ( C = O ) group. To avoid exceeding the octet on the C atom attacked by the nucleophile, the π bond is broken and the pair of electrons from the π bond becomes a lone pair on the more electronegative O atom. The immediate product of nucleophilic addition is often a strong base because it possesses a relatively unstable negative charge. Sometimes, species already present in the reaction mixture, such as the solvent, are acidic enough to protonate that product. Otherwise, we can carry out this protonation by adding an acid in a subsequent acid workup.

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
