Question

Statement 1:The green manganate is paramagnetic but the purple permanganate is diamagnetic in nature. Statement 2: MnO2-4 contains one unpaired electron while in MnO-4 all electrons are paired (A) If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1. (B) If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1. (C) If Statement 1 is true but Statement 2 is false. (D) If Statement 1 is false but Statement 2 is true

Statement 1: Correct statement and reason is correct explanation of assertion.
Green

\to M n O_{4}^{2 -} - [A r]^{18} 3 d^{1} 4 s^{0}

there is one unpaired electron, so paramagnetic.
Purple

\to M n O_{4}^{2 -} - [A r]^{18} 3 d^{0} 4 s^{0}

here all electrons are paired, so diamagnetic

Q. Statement 1:The green manganate is paramagnetic but the purple permanganate is diamagnetic in nature.
Statement 2: $M n O_{4}^{2 -}$ contains one unpaired electron while in $M n O_{4}^{-}$ all electrons are paired

If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1.

If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1.

If Statement 1 is true but Statement 2 is false.

If Statement 1 is false but Statement 2 is true

Statement 1: Correct statement and reason is correct explanation of assertion.
Green $\to M n O_{4}^{2 -} - [A r]^{18} 3 d^{1} 4 s^{0}$ there is one unpaired electron, so paramagnetic.
Purple $\to M n O_{4}^{2 -} - [A r]^{18} 3 d^{0} 4 s^{0}$ here all electrons are paired, so diamagnetic
