![**Valence Bond Theory**
**Objective:** Draw pictures of the bonding of the following molecules using valence bond theory.
### Molecules:
1. **Structure 1:**
- Atoms: Hydrogen (H), Nitrogen (N), Carbon (C), Oxygen (O)
- Arrangement: H-C ═ N⁺-CH₃
- The nitrogen atom is bonded to a carbon atom with a double bond and to a methyl group (CH₃) with a single bond. The nitrogen has a positive charge. Oxygen is bonded to carbon with a single bond and has three lone pairs, giving it a negative charge.
2. **Structure 2:**
- Atoms: Hydrogen (H), Carbon (C), Nitrogen (N)
- Arrangement: H₃C-N⁻═C-CH₃
- The carbon atom is connected to a nitrogen atom with a double bond, and this nitrogen has a lone pair, giving it a negative charge. There are two methyl groups (CH₃) bonded to the carbon atoms.
**Instructions:**
- Analyze the electron configuration of each atom in the molecules.
- Determine the hybridization state of each atom involved in bonding.
- Illustrate the overlapping of atomic orbitals to form sigma (σ) and pi (π) bonds.
- Include any relevant lone pairs and depict charge distribution where electrons are shared or transferred.
This exercise will help visualize the molecular structure and bonding interactions according to valence bond theory.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0c9cc737-bc69-4364-ac27-de0ca112dbcd%2F79e15c25-605d-446d-938c-50bb4188edfc%2F6bj63ul_processed.jpeg&w=3840&q=75)
