Single Choice

The electronegativities of nitrogen and chlorine are almost same. However, $$NH_3$$ exists as liquid whereas $$HCl$$ as gas due to __________ between the molecules of $$NH_3$$.

Avan der Walls force of attraction
Bionic bonding
CH-bonding
Correct Answer
Ddipole-dipole interaction

Solution

Due to H-bonding in $$NH_3$$ molecule. It is liquid but there is presence of van der Waal force in between $$HCl$$ molecules instead of H-bonding so it is gas.

Hence, option C is correct.
