JEE CHEMISTRY MCQ: CHEMICAL BONDING & MOLECULAR STRUCTURE

1 Medium

1 of 1

Analyzing +4 | -1

Assertion(A) All

{F}-{S}-{F}

angles in

{SF}_4

are greater than

90^{\circ}

but less than

180^{\circ}

.

Reason(R) The lone pair-bond repulsion is weaker than bond pairbond repulsion.

View answer and explanation

Correct option: C

If (A) is correct but (R) is incorrect.

The correct answer is C (If (A) is correct but (R) is incorrect) because the assertion about F-S-F angles in SF4 is true, but the reason regarding lone pair-bond pair repulsion is stated incorrectly.
