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:

In the light of the above statements, choose the correct answer from the options given below:
Option 1 -
A is false but R is true
Option 2 -
Both A and R are true, and R is the correct explanation of A
Option 3 -
A is true but R is false
Option 4 -
Both A and R are true, but R is not the correct explanation of A

1 Answer
-
Correct Option - 4
Detailed Solution:H? O has a tetrahedral geometry and a bent shape with a bond angle of 104.5°, which is smaller than 109.5°. This is because of the presence of two lone pairs in H? O.
