In which of the following set of molecules is the order of boiling point incorrect?

A

Xe `gt` Ar `gt` He

B

HF `gt` HCI `gt` HBr

C

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

D

`C_(3) H_(8) gt C_(2) H_(6) gt CH_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
Among HF,HCI and HB boiling point of HF is the highest. Out of HCI and HBr, HBr has a higher boiling point due to increase in molecule size or molecule size or molecular mass. Thus option (b) is incorrect .
