###### FREE Expert Solution

We’re being asked to figure out the electronic configuration of CN and to determine which of the given statements is correct based on its molecular orbital diagram.

Let’s first draw the molecular orbital diagram for CN.

Step 1: Calculate the total valence electrons present.
Step 2: Fill the molecular orbitals with electrons.

Step 1: Calculate the total valence electrons present.

Group             Valence Electrons
C         4A                   1 x 4 e- = 4 e-
N         5A                   1 x 5 e- = 5 e-
__________________________________
Total: 9 valence e-

Step 2: Fill the molecular orbitals with electrons.
