Question

Statement 1. `Fe^(2+)`ion has 24 electrons and its electronic configuration represents that of Cr (Z=24).
Statement 2. All the five unpaired electrons, in the 3d sub shell give stability to the ion.
A. Statement-1 is true , Statement-2 is also true.
Statement-2 is the correct explanation of Statement-1
B. Statement-1 is true , Statement-2 is also true.
Statement-2 is not correct explanation of Statement-1

D. Statement-1 is false, Statement-2 is true.

Answer 1

Correct Answer - D
Correct statement-1. Statement 1 is false . The two configurations are different.
`F^(2+) : [Ar]^(18)3d^(6)`
`Cr : [Ar]^(18) 4s^(1)3d^(5)`
