Aldehydes and ketones cannot undergo nucleophilic additionelimination reactions because:
 a. they are extremely stable molecules and do not react chemically in most cases.
 b. they do not have an electronegative atom attached to the carbonyl group to act as a good leaving group.
  c. they do not have an electronegative atom attached to the -carbon to act as a good leaving group.
 d. the bond angles in these molecules are not conducive for simultaneous nucleophilic addition and elimination.

Question 2

If D-phenylalanine is prepared from an aldehyde compound, the chemicals that would be used are:
 a. KMnO4 and hot HNO3.
  b. NaBH4.
 c. CH3MgCl in ether.
 d. NH2OH.
