Question

Which of these molecules does not show Hydrogen Bonding?

(a) HBr

(b) HF

(c) NH_3

(d) H_2O

Solution:

Hydrogen bonding occurs between hydrogen and more electronegative

elements like Oxygen, Fluorine and Nitrogen. It does not occur

with Bromine as it is less electronegative compared to the other

three.

Therefore option (a) is correct.
