JEE Main 2023 — d and f Block Elements Question with Solution

JEE Main 2023 (08 Apr Shift 1)

Question

In chromyl chloride, the number of d-electrons present on chromium is same as in (Given at no. of Ti : 22, V : 23, Cr : 24, Mn : 25, Fe : 26)

Correct answer
B Mn (VII)

Step-by-step explanation

In chromyl chloride (CrO2Cl2), the oxidation state of chromium (Cr) is +6.

So, Cr (VI) = [Ar]18 3d0

For the given elements the configuration is,Mn(VII) = [Ar]18 3d0

Fe(III) = [Ar]18 3d5

Ti(III) = [Ar]18 3d1

V(IV) = [Ar]18 3d1

So among the given options Mn(VII) and Cr (VI) will have same number of d-electrons.
