**Exercise: Analyzing Molecular Structure**

Please redraw the following molecular structure on your paper. Once you have done so, complete the tasks outlined below:

1. **Hybridization:**
   - Label the hybrid orbital type (e.g., sp, sp², sp³, d, etc.) for each atom in the molecule, excluding the hydrogen atoms.

2. **Bond Angle:**
   - Estimate the approximate carbon-carbon-oxygen bond angle.

3. **Molecular Geometry:**
   - Determine the molecular geometry of the oxygen atom.

4. **Bond Count:**
   - Calculate the total number of sigma (σ) bonds and pi (π) bonds present in the molecule.

**Structure:**

**Notes:**

- The diagram features a molecule with carbon, nitrogen, and hydrogen atoms. 
- A triple bond is indicated with the “≡” symbol between carbon and nitrogen atoms.
- Lone pairs are shown as pairs of dots, particularly around the oxygen atom.
- Bond angles and lone pairs are important for determining the hybridization and molecular geometry.

Expert Solution
Step 1

A. If l.p. + sigma bonds around an atom are 4, 3 and 2 respectively then hybridization of that atom will be sp3, sp2 and sp respectively.

Also, if no. of π bonds around an atom are 0, 1 and 2 respectively then hybridization of that atom will be sp3, sp2 and sp respectively.

On the basis of this the left N atom is sp2 hybridized while the right N atom is sp hybridized. The C atom attached to right N is sp hybridized. The another C atom attached to O atom is sp2 hybridized. The O atom is sp3 hybridized.

B. The C-C-C bond angle for sp3, sp2 and sp hybridization respectively involves bond angle of 109.5°, 120° and 180° respectively.

As C-C-N middle C is sp2 hybridized, the C-C-N atom has 120° bond angle as it is sp2 hybridized.
