41) Reducing agents, such as [ Na,Cr,0,/ DMSO & (CH,CH2),N / NABH, ], increase the number of [ electrons / bonds to an oxygen / bonds to a hydrogen ] in the structure of a target molecule. 42) Of the (functional group) derivatives, [ acid chloride / acid anhydride / amide ] is the most reactive while [ ester / acid anhydride / amide ] is the least reactive. 43) Hydrolysis of an ester under acidic conditions leads to products with and functional groups.
