Question

Which one of the following molecules will form a linear polymeric structure due to hydrogen bonding?
(a) HCl (b) HF (c) H2O (d) NH3

Answer 1

Answer:

This is known as a hydrogen bond. Hydrogen bonds are attractions between a $\delta + $ hydrogen on one molecule and a lone pair on a very electronegative atom on another molecule. Whereas, no hydrogen bonding exists between HCl, and ${H_2}O$ also has a cage-like structure. Hence, option D is correct.
