Explanation: A primary amine has the group –NH2 attached to one carbon (R–NH2). Checking the options:

  • (CH3)3N: tertiary amine (N bonded to three carbons) → not primary.
  • CH3NH2: methylamine, R–NH2 → primary amine.
  • CH3CONH2: an amide, not an amine.
  • (CH3)2NH: secondary amine (N bonded to two carbons).
