Which of the following orders of boiling points of hydrides of Group 16 is correct?

A

`H_(2)Ogt H_(2),Sgt H_(2),Se`

B

`H_(2),O gt H_(2),Slt H_(2)Se `

C

`H_(2)O lt H_(2) S gt H_(2) Se`

D

`H_(2) O lt H_(2)S lt H_(2) Se`

Text Solution

Verified by Experts

The correct Answer is:
B
Because of hydrogen bonding, the boiling point of `H_(2),O` is greater than that of `H_(2)S`. The boiling point of `H_(2),S` is smaller than `H_(2), ` Se as the former is a lighter molecule.
