Question

Assertion: All F-S -F angle ln SF₄ is greater than 90° but less than 180°

Reason : The lone pair-bond pair repulsion is weaker than bond pair-bond pair repulsion.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option (c) A is true but R is false  

Explanation:

Due to greater lone pair - bond pair repulsions, than bond pair - bond pair repulsions, the F - S -F bond angle decreases from 180°.
