**Exercise: Resonance Structures and IR Frequencies**1. **Resonance Structures** - Draw 3 additional resonance structures that demonstrate which atoms have partial positive character. - Structure provided: A benzene ring attached to a carbon triple-bonded to a nitrogen (isocyanide).2. **Infrared Frequencies** - The NH bonds in ammonia have an IR frequency of 3335 cm⁻¹, while the PH bonds in phosphine have an IR frequency of 2327 cm⁻¹. In a single sentence, describe the reason for the difference.**Explanation:**- **Diagram Description**: The initial structure shown illustrates a benzene ring connected to a C≡N group. This setup requires additional resonance structures to highlight partial positive charges on different atoms.- **Reason for IR Frequency Differences**: The difference in IR frequencies is due to the stronger N-H bond in ammonia compared to the P-H bond in phosphine, resulting from nitrogen's higher electronegativity and bond strength.

For a molecule we can write two or more Lewis structures which differ in the position of electrons…
