Hydrazine is an inorganic compound with the chemical formula H 2NNH 2 (also written N 2H 4). It is a colorless flammable liquid with an ammonia-like odor.Hydrazine is highly toxic and dangerously unstable unless handled in solution.ydrazine can arise via coupling a pair of ammonia molecules by removal of one hydrogen per molecule. Each H 2 N-N subunit is pyramidal in shape. The N-N single bond distance is 1.45 A (Ã¥ 145), pm and the molecule adopts a gauche. Conformation the rotational barrier is twice that of. ethane
