Question

Assertion H-S-H bond angle in H$_2$S is closer to 90$^{\circ}$ but H-0-H bond angle in H$_2O$ is 104.5$^{\circ}$.
Reason $lp-lp$ repulsion is stronger in $H_2S$ than in H$_2O$.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
• C. Assertion is true but Reason is false
• D. Both Assertion and Reason are false.

Answer 1

Answer: (C)

Lone pair-bond pair repulsion, is strong in H$_2$S as bond pair-bond pair repulsion becomes weak with increase in size of central atom.
