The highest electrical conductivity of the following aqueous solutions is of

Options

A. `0.1M` fluroacetic acid
B. `0.1M` difuoroacetic acid
C. `0.1M` acetic acid
D. `0.1M` chloroacetic acid

Answer

To determine which aqueous solution has the highest electrical conductivity among the given options, we need to analyze the compounds based on their acidity and the resulting concentration of hydrogen ions (H⁺) they produce in solution. The more H⁺ ions produced, the higher the conductivity.

### Step-by-Step Solution:

1. **Identify the Compounds**:
- Option 1: 0.1 M Fluoroacetic Acid (CH₂FCOOH)
- Option 2: 0.1 M Difluoroacetic Acid (CCl₂FCOOH)
- Option 3: 0.1 M Acetic Acid (CH₃COOH)
- Option 4: 0.1 M Chloroacetic Acid (CH₂ClCOOH)

2. **Understand Acidity**:
- The acidity of a compound is influenced by the presence of electron-withdrawing groups (EWGs). EWGs increase the acidity by stabilizing the negative charge on the conjugate base after the acid donates a proton (H⁺).

3. **Analyze Each Compound**:
- **Fluoroacetic Acid**: Has one fluorine atom, which is an EWG, making it more acidic than acetic acid.
- **Difluoroacetic Acid**: Has two fluorine atoms, significantly increasing its acidity compared to the others.
- **Acetic Acid**: Has no EWG and is the least acidic among the options.
- **Chloroacetic Acid**: Has one chlorine atom, which is also an EWG but is less effective than fluorine.

4. **Comparative Acidity**:
- The order of acidity based on the presence of EWGs is:
- Difluoroacetic Acid > Chloroacetic Acid > Fluoroacetic Acid > Acetic Acid
- Since difluoroacetic acid is the most acidic, it will dissociate more in solution, producing more H⁺ ions.

5. **Conclusion**:
- Since difluoroacetic acid produces the highest concentration of H⁺ ions in solution, it will have the highest electrical conductivity among the given options.

### Final Answer:
The highest electrical conductivity of the following aqueous solutions is of **0.1 M Difluoroacetic Acid**.
