Question

which compound , on reaction with hydrogen cyanide , produces a compound with chiral centre ?
a) CH3CHO
b) CH3CH2COCH2CH3
C) CH3CO2CH3
D)HCHO

Answer 1

its CH3CHO
while cyanide attack to other molecules will produce the achiral molecules where out of four groups on carbon atom ,2 groups will be similar hence they are not said to be chiral
a carbon is said to be chiral if it makes all 4 bonds with different groups:)
