Question

For the given species - $N_2,CO,C{N}^{-}$and $N{O}^{+}$, which of the following statement(s) is/are true for these?

• A. All species are paramagnetic.
• B. The species are isoelectronic.
• C. All the species have dipole moment.
• D. All the species are linear.

Answer 1

Answer: (B), (D)

The species are isoelectronic.
All the species are linear.

$N_2$ is a non-polar compound Hence it doesn't have a dipole moment. Therefore option $C$ is a wrong statement.

$N_2$ doesn't have any unpaired electrons. So, it's not paramagnetic.

Option (A) is the wrong statement.

All the species have 14 electrons in their valence shell. Thus, all the species are isoelectronic.

Thus, statement B is correct.

Also, all the species are linear.

Thus, option D is correct.
