H 2 S e has higher boiling point than H 2 S . This is best explained by
Options
- AHigher extent of hydrogen bonding in H 2 S e
- BHigher polarity of H 2 S
- CHigher polarity of H 2 S e
- DHigher dispersion forces in H 2 S e due to its higher molecular weight.
Correct answer
D. Higher dispersion forces in H 2 S e due to its higher molecular weight.
Step-by-step solution
Both H 2 S e and H 2 S are polar but the former has higher dispersion forces due to its higher molecular weight and hence the higher boiling point.
