amina poate fi CH3CH2-N-(CH3)2 => B = etildimetilamina
100% ................................. 40%
14n+32 .......................... 12n
=> n = 2 => D = acid acetic
=> CH3-N(CH3)-COCH3 = A
CH3-N(CH3)-COCH3 + 2H2 --> CH3CH2-N-(CH3)2 + H2O (C)
CH3-N(CH3)-COCH3 + H2O --> CH3COOH (E) + CH3-NH(CH3)
CH3-NH(CH3) + CH3I --> CH3-N(CH3)2 => trimetilamina => D.
