1.1.3 \( \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH} \) \( 1.1 .4 \mathrm{C}_{4} \mathrm{H}_{3} \mathrm{OHOR} \mathrm{CH} \) 3 \( \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{OH} \) The general formula of carbohydrates is for glucose molecule will be 3 Draw the structural formulae and Lewis structure of the following alkanes:

To address your request, let's break it down step by step. ### Step 1: Identify the Compounds 1. **\( \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH} \)**: This is acetic acid (ethanoic acid). 2. **\( \mathrm{C}_{4} \mathrm{H}_{3} \mathrm{OH} \)**: This appears to be a typo or incomplete formula. It could refer to a compound like butanol or phenol, but we need clarification. 3. **\( \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{OH} \)**: This is propanol (specifically, 1-propanol). ### Step 2: Draw Structural and Lewis Structures #### 1. Acetic Acid (\( \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH} \)) - **Structural Formula**: ``` O || H3C-C-OH | H ``` - **Lewis Structure**: ``` H O | || H3C-C-O-H | H ``` #### 2. Butanol or Phenol (\( \mathrm{C}_{4} \mathrm{H}_{3} \mathrm{OH} \)) - Assuming it is **Butanol** (\( \mathrm{C}_{4} \mathrm{H}_{10} \mathrm{O} \)): - **Structural Formula**: ``` H H H | | | H3C-C-C-C-OH | | | H H H ``` - **Lewis Structure**: ``` H H H | | | H3C-C-C-C-O-H | | | H H H ``` - If it is **Phenol** (\( \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{OH} \)): - **Structural Formula**: ``` OH | C6H5 ``` - **Lewis Structure**: ``` O | C6H5 ``` #### 3. Propanol (\( \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{OH} \)) - **Structural Formula**: ``` H H H | | | H2C-CH2-CH-OH | | H H ``` - **Lewis Structure**: ``` H H H | | | H2C-CH2-CH-O-H | | H H ``` ### Summary - The structural and Lewis structures for acetic acid, butanol (or phenol), and propanol have been provided. If you need further clarification or if the second compound needs to be specified, please let me know!
