Question

Assertion :The number of bonding electrons in $N_2$ and $N_2^{-}$ is same. Reason: The bond order and bond length of $N_2^{+}$ and $N_2^{-}$ are same.

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 C

Assertion is true, Reason is false

The bond order $N_2^{+}$ and $N_2^{-}$ is same. The bond order of both the specie is $2.5$. But the B.E of $N_2^{+}>4\times$ B.E of $N_2^{-}$
Hence, Assertion is true, Reason is false.
