Assertion (A) : IE(1) of Mg is greater t...

Assertion (A) : `IE_(1)` of `Mg` is greater than that of `Al`.
Reason (R ) : It is easier to remove an electron fro `3s` orbital than from `3p` orbital.

A

If both A and R are correct and R is the correct explanation for A.

B

If both A and R are correct and R is not the correct explanation for A.

C

If A is correct and R is incorrect

D

If A is incorrect and R is correct

Text Solution

Verified by Experts

The correct Answer is:
C
`IE_(1)` of `Mg gt IE_(1)` of `Al`. Assertion is correct.
Correct reason : It is easier to remove an electron from `3p` orbital than from `3s` orbital (due to pentration effect).
