Assertion (A): All bond lengths are equal in but different in
Reason (R): Hybrid state of central atom is different in Both molecules.
Reason (R): Hybrid state of central atom is different in Both molecules.
View answer and explanation
Correct option: B
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
Option B (Both (A) & (R) are true but the (R) is not the correct explanation of the (A)) is correct because both the assertion and the reason are true, but the reason does not explain the assertion. The difference in bond lengths in is due to axial and equatorial positions, not just the hybridization.
