H(2)O is liquid while H(2)S is a gas at ...

`H_(2)O` is liquid while `H_(2)S` is a gas at room temperature. Explain.

A

electronegativity of O is greater than S

B

difference in the bond angles at both molecules

C

association takes place in `H_(2)O` due to H-bonding while no H-bonding in `H_(2)S`

D

O and S belong to different periods.

Text Solution

Verified by Experts

The correct Answer is:
C
Since, at room temperature or any temperature, `H_(2)O` molecules possesses H-bonding while, `H_(2)S` does not possess this bonding. Therefore, `H_(2)O` is a liquid but `h_(2)S` is a gas.
