### Structural Formula Representation **Educational Task:** #### Objective: - Draw an (a) expanded structural formula and (b) a line formula corresponding to the following condensed structural formula. #### Given Condensed Structural Formula: - CH₃O(CH₂)₄CHBr(CH₂)₂OCH₂CH₂CN ### Instructions: **1. Expanded Structural Formula:** - In an expanded structural formula, all atoms and bonds in the molecule are shown explicitly. This includes displaying hydrogen atoms bonded to carbons. **2. Line Formula:** - In a line formula, also known as a skeletal formula, carbon atoms are implied at each vertex and line endpoint. Hydrogen atoms attached to carbons are generally omitted, with the assumption that carbons have the correct number of hydrogen atoms to fill their valency of four. ### Breakdown of the Given Condensed Structural Formula: - **CH₃O-**: This segment indicates a methoxy group. - **(CH₂)₄-**: Four methylene groups sequentially connected. - **CHBr-**: A carbon attached to a bromine atom. - **(CH₂)₂-**: Two additional methylene groups. - **OCH₂CH₂-**: An ethoxy group. - **CN**: A nitrile group. ### Graphical Representation: #### (a) Expanded Structural Formula: Depict each atom and bond clearly, showing all hydrogen atoms explicitly. #### (b) Line Formula: Simplify the structure by only displaying the carbon chain as vertices and endpoints. ### Example Diagram: **Expanded Structural Formula:** 1. Methoxy group (CH₃O-) attached to: 2. A chain of four CH₂ groups ((CH₂)₄), followed by: 3. A carbon bonded to a bromine (CHBr). This carbon also continues the chain with: 4. Two more CH₂ groups ((CH₂)₂), which leads to: 5. An oxygen linked to two CH₂ groups (OCH₂CH₂). 6. Finally, the structure ends with a cyanide group (CN). **Line Formula:** - Draw the linear carbon backbone: ``` CH₃-O-(CH₂)₄-CHBr-(CH₂)₂-O-CH₂-CH₂-CN ``` Use these instructions to sketch both structures for a clear representation of the molecule in different formats.
