Amongst H 2 O , H 2 S , H 2 S e and H 2 T e , the one with the highest boiling point is –
Options
- AH 2 O because of hydrogen bonding
- BH 2 T e because of higher molecular weight
- CH 2 S because of hydrogen bonding
- DH 2 S e because of lower molecular weight
Correct answer
A. H 2 O because of hydrogen bonding
Step-by-step solution
Boiling point trend is H 2 O > H 2 T e > H 2 Se > H 2 S . H 2 O is highest due to H - bonding
