Explain why the product of nucleophilic addition of a cyanide ion to the ketone CH3COCH2CH3 shows no optical activity
The ketone group is planar and the cyanide ion has equal chance of attacking above or below the plane. Therefore a racemic mixture of the product is formed and the product shows no optical activity
