Statement-1 : The number of paired electrons in the following gaseouos ions `Mn^(3+) , Cr^(3+) , V^(3+)` and `Ti^(3+)` are `4,3,2` and `1` respectively.
Statement-2 : `Cr^(3+)` is most stable in aqueous solution among these ions.
(A) Statement-1 is True, Statement-2 is True: Statement-2 is a correct explanation for Statement-1.
(B) Statement-1 is True, Statement-2 is True: Statement-2 is NOT a correct explanation for Statement-1.
(C) Statement-1 is True, Statement-2 is False
(D) Statement-1 is False, Statement-2 is True

Explanation

`Mn^(3+) = [Ar]^(18)3d^(4), Cr^(+3) = [Ar]^(18)3d^(3), V^(3+) = [Ar]^(18) 3d^(2), Ti^(3+) = [Ar]^(18)3d^(1)Cr^(3+)` is most stable in aqueous solution because it has half filed `t_(2g)^(3)` energy level of `3d` orbitals in octahedral crystal field spliting and accoding to crystals field theory (CFT) it has highest value of CFSE i.e. `1.2.D_(O)`.
