This question has statement I and Statement II. Of the four choices given after the statements, choose the one that best describes the two Statements. (1) Statement-I is true, Statement-II is true, Statement-II is a correct explanation of Statement-I (2) Statement-I is true, Statement-II is true,Statement-II is not a correct explanation of Statement-I (3)Statement-I is a true , Statement-II is false (4) Statement-I is false, Statement-II is true Statement-I: All F-S-F angles in SF_4 are greater than 90^@ but less than 180^@ Statement-II: The lone pair-lone pair repulsion is greater than pair-bond pair repulsion.

Explain why : Lone pair-lone pair repulsion is more than the bond pair-bond pair repulsion?

Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R: Assertion A: The H-O-H bond angle in water molecule is 104.5^(@) Reason R: The lone pair - lone pair repulsion of electrons is higher than the bond pair - bond pair repulsion. In the light of the above statements, choose the correct answer from the options given below:

Assertion :- The observed bond angle in NH_3 molecule is less than 109^@ 28 '. Reason :-In ammonia molecule, the bond pair-bond pair repulsion is more than the lone pair-bond pair repulsion

Repulsion between bond pair-bond pair is less than in between lone pair -lone pair.

S_1 : Bond angle of H_2O is 104.5^@ . S_2 : In H_2O the lone pair- lone pair repulsion overcomes the bond pair- bond pair repulsion

Assertion (A): The bond angle in HOH ( H_2O ) decreases from 109^@ 28' to 104^@ 31' . Reason (R) : H_2O has lone pair - lone pair repulsion and lone pair - bond pair repulsion.

Repulsion between bond pair-bond pair is than in between lonepairlone pair.
