1.	In the reaction CH3CHO + HCN → CH3CH(OH)CN, a chiral centre is produced. This product is(a) dextrorotatory (b) racemic mixture(c) meso compound (d) laevorotatory.
Answer» The correct option is (b). Explanation: As during the reaction, a chiral carbon is created and further since the CN^- ion can attack the planer aldehyde group both from the top and the bottom face of the aldehyde group with equal case, therefore, a 50-50 mixture of the two enantiomers, that is, a racemic mixture is obtained.
