Vedclass · Answer

(C) In the Claisen condensation of two different esters,both having $\alpha$-hydrogens,a total of $4$ products are formed: $2$ self-condensation products and $2$ cross-condensation products.The cross-condensation products are formed as follows:$1.$ The enolate of $CH_3COOC_2H_5$ attacks the carbonyl carbon of $C_6H_5CH_2COOC_2H_5$.$2.$ The enolate of $C_6H_5CH_2COOC_2H_5$ attacks the carbonyl carbon of $CH_3COOC_2H_5$.Therefore,the total number of cross-condensation products is $2$.

Number of cross-condensation products in the given reaction: $CH_3COOC_2H_5 + C_6H_5CH_2COOC_2H_5 \xrightarrow[C_2H_5OH]{C_2H_5ONa}$
