WebSince hydrogen bonding gives rise to links in water molecules, it results in higher boiling and melting points than other chemicals. Since there is hydrogen bonding in NH 3 and no hydrogen bonding in PH 3, ammonia possesses a high boiling point. As ethanol has hydrogen bonds, its boiling point is higher than diethyl ether. Conclusion
