Arrange the following in order increasing boiling point 

Option: 1

\mathrm{H_2O< H_2S< H_2Se< H_2Te}


Option: 2

\mathrm{H_2S< H_2O< H_2Se< H_2Te}


Option: 3

\mathrm{H_2S< H_2Se< H_2O< H_2Te}


Option: 4

\mathrm{H_2S< H_2Se< H_2Te< H_2O}

The boiling point increases with the increase of vander waal forces between the molecules and the vander waal molecules increase with the increase of size of molecule. The abnormally high boiling point of H_2 O can be explained by hydrogen bonding.

The values of boiling point and some other properties of the hydrides of Group 16 elements are given below

Therefore, option (4) is correct.
