Question

Assertion :$N{O}^{+}$ is more stable than the $NO$, and $C{O}^{+}$ is less stable than $CO$. Reason: $N{O}^{+}$ formed when NO has lost an antibonding electron and $C{O}^{+}$ formed when CO has lost B.M.O. $e^{-}$ having anti-bonding character.

Read the above assertion and reason and choose the correct option regarding it.

• A. Assertion is true, Reason is true and Reason is correct explanation for Assertion
• B. Assertion is true, Reason is true and Reason is NOT the correct explanation for Assertion
• C. Assertion is true, Reason is false
• D. Assertion is false, Reason is true

Answer 1

The correct option is A

Assertion is true, Reason is true and Reason is correct explanation for Assertion

$N{O}^{+}$ formed when $NO$ has lost an antibonding electron.

So, $N{O}^{+}$ is more stable than the $NO$.

$C{O}^{+}$ formed when $CO$ has lost bonding molecular orbital $e^{-}$ having anti-bonding character.

So, $C{O}^{+}$ is less stable than the $CO$.

Thus, Assertion is true, Reason is true and Reason is correct explanation for Assertion.
