Certain cyclic 1, 3-diketone give, under Clemmensen reduction, a fully reduced product along with a monoketone with ring contraction. Explain.

Nitrous acid reacts with all classes of amines. The product obtained from these reactions depend on whether primary, secondary or tetriary and ,wheather the amine or aliphatic or aromatic. Aliphalic primary amines react with acid (NaNO_(2)+HCl) to form alcohol as major product. In , addition to alcohol, alkene and alkyl halides are also formed as minor product. Certain cyclic primary amines can undergo either ring expansion or ring contraction reactions on treatment with acid. This reaction is called Demajanov ring expansion or contraction. What will be the major product when 2-aminopropane is treated with nitrous acid?

Certain dicarboxylic acids spontaneously eliminate water when heated forming cycioc anhydirides. But for the reaction to be successfully. The cyclic anhydrides product must normally have a ring size of fivee or six members. There are two important reasons, first, the second carboxyl group can serve as the acid catalyst (by intramolecular proton transfer), as well as the nucleophile. And second, the high temperature involved reduce the need for catalyst. Which of the following dicarboxylic acid will not for cyclic anhydrides?
