Symptoms of acute (short-term) exposure to high levels of hydrazine may include irritation of the eyes, nose, and throat, dizziness, headache, nausea, pulmonary edema, seizures, coma in humans. Acute exposure can also damage the liver, kidneys, and central nervous system.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
