The order of ...

Question

The order of boiling point of the following substances is :

$N H_{3} > P H_{3} > A s H_{3} > S b H_{3} > B i H_{3}$

If the given order is true enter 1 else 0.

Solution

The boiling point of ammonia is greater than the boiling point of phosphine and AsH $_{3}$ because of H-bonding. Then the boiling point increases down the group as the atomic size increases.
$N H_{3} (238.5 K) > P H_{3} (185.5 K) < A s H_{3} (210.6 K) < S b H_{3} (254.6 K) < B i H_{3} (290 K)$

Hence the correct answer is 0.
