Solution

Solution Steps

Step 1: Identify the Structures

First, we need to identify the given structures:

\(: \ddot{\mathrm{O}}-\mathrm{C} \equiv \mathrm{N}:\)
\(\ddot{\mathrm{O}}=\mathrm{C}=\dot{\mathrm{N}}\)

Step 2: Analyze Bond Orders

In the first structure, the bond orders are:
- O-C: single bond
- C-N: triple bond
In the second structure, the bond orders are:
- O=C: double bond
- C=N: double bond

Step 3: Check for Resonance Criteria

Resonance structures must:

Have the same arrangement of atoms.
Have the same number of electrons.
Differ only in the arrangement of electrons (bonding and lone pairs).

Step 4: Compare the Structures

The first structure has a single bond between O and C and a triple bond between C and N.
The second structure has double bonds between O and C, and C and N.
The bond orders are different in the two structures.
