Solution:
QUESTION: 8

  + CH3CH2CH2CH2 NH2  X, X is

Solution: The lone pairs of nitrogen will attack at the nucleophilic carbonyl carbon.. 1 mole HCĺ will get eliminated.
again the lone pair of N will attack like previous one and another mole HCl will get eliminated.
in this whole method the carbon chain attached to nitrogen atom will stay unaffected.
hence option c is correct.
