Which of the following hydeides has the lowest boiling point?

A

`H_(2)O`

B

`H_(2)S`

C

`H_(2)Se`

D

`H_(2)Te`

Text Solution

Verified by Experts

The correct Answer is:
B
`{:(H_(2)O,H_(2)S,H_(2)Se,H_(2)Te),(373K,213K,269 K,232K):}`
`H_(2)S` has lowest boiling point and `H_(2)O` has highest boiling point because due to H-bonding the boiling point of `H_(2)O` is high.
