The correct order of increasing boiling point is

A

`H_(2)S, H_(2)O, H_(2)Te, H_(2)Se`

B

`H_(2)O, H_(2)S, H_(2)Se, H_(2)Te`

C

`H_(2)Te, H_(2)Se, H_(2)S, H_(2)O`

D

`H_(2)S, H_(2)Se, H_(2)Te, H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
D
As the size increases from S to Te, the van der Waals forces of attraction interacting the molecules `H_(2)M` increase and hence the boiling point increases in that order. However, water has the highest boiling point because of intermolecular H - bonding. Thus, `H_(2)S` has the lowest boiling point.
