Correct answer is (c) PH 3< AsH 3< NH 3

Q. What is the correct order when the substances are arranged in the order of their boiling points?

$N H_{3} < P H_{3} < A s H_{3}$

$A s H_{3} < P H_{3} < N H_{3}$

$P H_{3} < A s H_{3} < N H_{3}$

$A s H_{3} < N H_{3} < P H_{3}$

Correct answer is (c) $P H_{3} < A s H_{3} < N H_{3}$

Q. What is the correct order when the substances are arranged in the order of their boiling points?

NH3​<PH3​<AsH3​

AsH3​<PH3​<NH3​

PH3​<AsH3​<NH3​

AsH3​<NH3​<PH3​

Correct answer is (c) PH3​<AsH3​<NH3​

$N H_{3} < P H_{3} < A s H_{3}$

$A s H_{3} < P H_{3} < N H_{3}$

$P H_{3} < A s H_{3} < N H_{3}$

$A s H_{3} < N H_{3} < P H_{3}$

Correct answer is (c) $P H_{3} < A s H_{3} < N H_{3}$
