Match List I (Molecules) with List II (Boiling points) and select the correct answer

Options

A. A – iii, B – ii, C – v, D – iv, E – i
B. A – v, B – iii, C – ii, D – iv, E – i
C. A – i, B – iv, C – v, D – ii, E – iii
D. A – i, B – ii, C – iii, D – iv, E – v

Answer

B

Explanation

Except `NH_3` , boiling point smoothly increases down the group due to increase in magnitude of vander Waal’s force. Ammonia shows intermolecular H–bonding. Its boiling point is higher than `AsH_3` but lower than `SbH_3` .
