The increasing order of volatility of hydrides of group 16 elements is -

Options:

Answer:

Solution:

Volatility of hydrides $V I - A$ $= H_{2} S > H_{2} S e > H_{2} T e > H_{2} O$
$V o l a t i l i t y \propto \frac{1}{m o l e c u l a r w e i g h t}$
But $H_{2} O$ is least volatile due to $H -$ Bond.
So, order of volatility is $H_{2} O {< H}_{2} T e < H_{2} S e < H_{2} S$
