Assertion Both `N_(2)` and `NO^(+)` are diamagnetic substances.
Reason : `NO^(+)` is isoelectronic with `N_(2)` .

Options

A. If both (A) and (R) are correct, but (R) is not the correct explanation of (A).
B. If both (A) and (R) are correct, but (R) is not the correct explanation of (A)
C. If (A) is correct, but (R) is incorrect.
D. If both (A) and (R) are incorrect.

Answer

A

Explanation

Both `N_(2)` and `NO^(+)` with 14 electrons have electronic configuration : `sigma2s^(2) sigma^(*) 2s^(2) pi2p_(x)^(2)pi2p_(y)^(2)sigma2p_(z)^(2)`
