Show a carbonyl compound (toggle: aldehyde/ketone) with reaction pathways. The C=O is polarized: C is δ+ (electrophilic), O is δ- (nucleophilic). Reactions: 1) REDUCTION with NaBH₄ or LiAlH₄: C=O → C-OH. Aldehyde → 1° alcohol. Ketone → 2° alcohol. Reverse of oxidation! 2) NUCLEOPHILIC ADDITION with
