Arrange the following in increasing order of boiling points: (CH3)3 N,C2H5 OH, C2H2 NH2 |
|
Answer» The increasing order of boiling point is C2H5OH > C2H5NH2> (CH3)3N. N−H···N hydrogen bond is weaker than an O−H···O hydrogen bond, because the difference in electronegativity between nitrogen and hydrogen (3.0–2.1 = 0.9) is less than that between oxygen and hydrogen (3.5–2.1 = 1.4). |
