Vedclass · Answer

(B) Schiff base is formed by the reaction of a primary amine with an aldehyde or ketone,resulting in the formation of an imine $(R-CH=N-R')$.$1$. $C_2H_5NH_2 + HNO_2 \rightarrow C_2H_5OH + N_2 + H_2O$ (Alcohol is formed).$2$. $C_2H_5NH_2 + C_6H_5CHO \rightarrow C_6H_5CH=NC_2H_5 + H_2O$ (This is a Schiff base).$3$. $C_2H_5NH_2 + NOCl \rightarrow C_2H_5Cl + N_2 + H_2O$ (Alkyl chloride is formed).$4$. $C_2H_5NH_2 + C_6H_5SO_2Cl \rightarrow C_6H_5SO_2NHC_2H_5 + HCl$ ($N$-ethylbenzenesulfonamide is formed).Therefore,the product $b$ is a Schiff base.
