Question

The common features are among the species
${CN}^{-},CO,{NO}^{+}$ are:

• A. bond order three and isoelectronic
• B. bond order three and weak field ligands
• C. bond order two and $\pi$ acceptors
• D. isoelectronic and weak field ligands

Answer 1

The correct option is A bond order three and isoelectronic

Number of electrons in the spicies $C{N}^{-},CO,N{O}^{+}$ is $14e^{-}$, all have same configuration, has isoelectronic.

Bond order is $3$ for all hence, they have same bond order.
