Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

Question

### Formal Charge Calculation for Labeled Atoms

Understanding formal charge is essential for predicting the stability of molecular structures. In this section, we will specify the formal charge for certain atoms in two different molecular structures.

#### Structure 1:
This structure involves a molecule with a chain of nitrogen atoms bonded to a carbon atom (H3C) and each other.

1. **Labeled atoms in the first structure:**
- **a**: The nitrogen atom directly bonded to H3C.
- **b**: The nitrogen atom between the two other nitrogen atoms.
- **c**: The terminal nitrogen atom with a lone pair.

The formal charges for these atoms need to be evaluated and selected from the dropdown menu with options: +2, +1, 0, -1, -2.

#### Structure 2:
This structure involves a carbon ring with an embedded nitrogen atom and another carbon atom with a lone pair.

2. **Labeled atoms in the second structure:**
- **a**: The nitrogen atom embedded in the carbon ring.
- **b**: The carbon atom bonded to the nitrogen atom and another carbon atom.
- **c**: The carbon atom with a lone pair bonded to the b-labeled carbon atom.

Similar to Structure 1, you will use the dropdown menu options to specify the formal charges for these labeled atoms: +2, +1, 0, -1, -2.

#### Summary of Interaction:
- The first molecule predominantly consists of nitrogen atoms bonded linearly with one terminal nitrogen involved in a lone pair.
- The second molecule is a heterocyclic compound mostly made up of a carbon ring with one nitrogen atom and a lone electron pair on a carbon atom.

By understanding and calculating the formal charges for these designated atoms, we can better predict the stability and reactivity of these molecular structures. Make your selections carefully by considering the formal charge calculation rules: Valence Electrons - (Non-bonding Electrons + 1/2 Bonding Electrons).
