What is the formal charge on the bold atoms? Please draw lone pairs where needed

### Chemical Structures Explanation The image contains four chemical structures, each representing a distinct organic compound. Below is a detailed explanation of each: 1. **Structure 1: Pyridine Derivative** - **Description**: This compound is a heterocyclic aromatic amine, specifically a methylated pyridine. - **Details**: - It consists of a nitrogen atom (N) incorporated within a six-membered ring. - The ring includes five carbon atoms (C), with two of them having CH groups, one having a CH3 group (methyl group), and the remaining are hydrogen atoms (H). - The arrangement forms a cyclic, planar structure common in aromatic organic compounds. 2. **Structure 2: Ether** - **Description**: This is a simple ether. - **Details**: - It features an oxygen atom (O) connected to two ethyl groups (CH3-CH2). - The oxygen is bonded in the center, forming a bent structure typical of ethers, with CH3 groups on either side. 3. **Structure 3: Phosphine Derivative** - **Description**: This molecule is a derivative of phosphine, with a phosphorus atom (P) surrounded by three hydrogens and one methyl group. - **Details**: - The phosphorus atom lies at the center, connected to three hydrogen atoms (H) and one methyl group (CH3). - The geometry is tetrahedral, a common shape for such molecules, indicating sp3 hybridization. 4. **Structure 4: Nitrile** - **Description**: This compound is a nitrile. - **Details**: - It includes a carbon triple-bonded to a nitrogen atom (C≡N), forming a linear structure. - This group is attached to a single methyl group (CH3), indicating a methyl nitrile or acetonitrile. Each structure represents a foundational concept in organic chemistry, displaying a variety of functional groups and bonding patterns. These visual representations are crucial for understanding molecular behavior and interactions.
