Assertion (A): Among the two O-H bonds in `H_(2)O` molecule, the energy required to break the first O-H bond and the other O-H bond is the same.
Reason (R) This is because the electronic environment around oxygen is the same even after brekage of one O-H bond.

A

A and R both are correct, and R is the correct ecplanation of A.

B

A and R both are correct, But R is not the correct ecplanation of A .

C

A is true but R is false .

D

A and R both are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Correct A : The bond enthalpies of the two O-H bonds in H-O-H are not equal .
Correct R : This is because electronic environment around O is not same after breakage of one O-H
bond.
