Question

Which one of the following molecules will form a linear polymeric structure due to hydrogen bonding?

Solution

Correct option is

HF

 

(H―F⋯H―F⋯H―F) 

NH3 and H2O will form a 3-dimentaional polymeric structure and H-bonds in H–Cl are not very strong (as in H–F), so formation of polymeric structure is difficult.
