Assertion : All \(\mathrm{F}-\mathrm{S}-\mathrm{F}\) angle in \(\mathrm{SF}_{4}\) is greater than \(90^{\circ}\) but less than \(180^{\circ}\). Reason : The lone pair-bond pair repulsion is weaker than bond pair-bond pair repulsion.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
\(\mathrm{SF}_{4}\) has a see-saw geometry with a bond angle of \(102^{\circ}\) and \(173^{\circ}\left(\mathrm{sp}^{3} \mathrm{~d}\right.\) hybridization). According to VSEPR theory, lone pair - bond pair repulsions are greater than bond pair - bond pair repulsions. So the option (3) is correct.
