Question

Assertion :$N{O}^{+}$ and $C{N}^{-}$ both have same bond order and magnetism (i.e. magnetic property). Reason: $N{O}^{+}$ and $C{N}^{-}$ are isoelectronic species.

• 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 a NOT correct explanation for Statement-1.
• C. Statement-1 is True, Statement-2 is False.
• D. Statement-1 is False, Statement-2 is True.

Answer 1

The correct option is A Statement-1 is True, Statement-2 is True ; Statement -2 is a correct explanation for Statement-1.

Number of electrons $N{O}^{+}=7+8-1=14$

Number of electrons $C{N}^{-}=6+7+1=14$

Bond order $=\frac{10-4}{2}=3$

Both are diamagnetic

Option A is correct.
