Vedclass · Answer

(B) In a cross aldol condensation,the nucleophile (enolate) attacks the carbonyl carbon of the electrophile.Here,$CH_3CH_2CH_2CHO$ (butanal) acts as the nucleophile,forming an enolate at the $\alpha$-carbon: $CH_3CH_2CH^-CHO$.This enolate attacks the carbonyl carbon of $CH_3CH_2CHO$ (propanal) as the electrophile.The reaction is: $CH_3CH_2CHO + CH_3CH_2CH_2CHO \rightarrow CH_3CH_2-CH(OH)-CH(CH_2CH_3)-CHO$.The product formed is $2-$ethyl$-3-$hydroxypentanal.Hence,the correct option is $B$.

Which among the following is a possible product during cross aldol condensation between propanal (as electrophile) and butanal (as nucleophile)?
