Question

Consider the following reaction Propanal + Methanal = → ( ii ) Δ ( iii ) NaCN ( iv ) H 3 O + ( i ) dil . NaOH P roduct B ( C 5 H 8 O 3 ) The correct statement for product B is. It is, optically active and adds one mole of bromine, racemic mixture and is neutral, racemic mixture and gives a gas with saturated NaHCO 3 solution, optically active alcohol and is neutrall

MARKS App · Accepted Answer

Propanal and methanal undergo aldol condensation reaction with sodium hydroxide. The α , β -unsaturated compound undergo 1 , 4 - conjugated addition with cyanide ion gives a racemic mixture. The cyanide undergo acidic hydrolysis gives carboxylic acid. Carboxylic acid will give CO 2 gas, with NaHCO 3 solution
