Question
### Provide the Molecular Formula for the Skeletal Drawing Shown Below **Question 9 of 48** In this question, you are asked to determine the molecular formula of a given skeletal structure. The skeletal structure represents a molecule, and you need to identify the total count of each type of atom present in the molecule. #### Diagram Explanation: The skeletal drawing depicts a straight carbon chain with an amine group (NH₂) attached at the end. A skeletal formula simplifies organic structures in which carbon atoms are implied at the intersections of lines (vertices) and at the endpoints of lines. Hydrogen atoms attached to carbons are also implied and not explicitly shown. The structure can be broken down as follows: - A three-carbon chain (C-C-C) - Each carbon has sufficient hydrogen atoms to complete a total of four bonds. - An amino group (NH₂) is attached to the last carbon. #### Calculation of Formula: 1. **Carbons (C):** 3 carbons are represented in the chain. 2. **Hydrogens (H):** - The first carbon will have 3 hydrogen atoms (CH₃). - The second carbon will have 2 hydrogen atoms (CH₂). - The third carbon, being attached to NH₂, will have 2 hydrogen atoms associated. - The amine group (NH₂) adds 2 additional hydrogen atoms (total of 7 H atoms). 3. **Nitrogen (N):** 1 nitrogen atom is present. Summing these, the molecular formula can be deduced as \( \text{C}_3\text{H}_9\text{N} \). #### Answer Choices: A) \( \text{C}_3\text{H}_7\text{N} \) B) \( \text{C}_3\text{H}_8\text{N} \) C) \( \text{C}_3\text{H}_9\text{N} \) D) \( \text{C}_2\text{H}_7\text{N} \) E) \( \text{C}_4\text{H}_10\text{N} \) The correct answer is: **C) \( \text{C}_3\text{H}_9\text{N} \)**
