Statement I : Zn^(2+) is diamagnetic ...

Statement I : `Zn^(2+)` is diamagnetic
Statement II : The electrons are lost from 4s orbital to from `Zn^(2+)`

A

If both assertion and reason are correct and reason is correct explanation for assertion.

B

If both assertion and reason are correct but reason is not correct not correct explanation for assertion.

C

If assertion is correct but reason is incorrect.

D

If both assertion and reason are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Correct explanation. In `Zn^(2+)` ion (`d^(10)` configuration), all electron orbitals are paired.
