The highest electrical conductivity of the following aqueous solutions is of(1) 0.1 M acetic acid (2) 0.1 M chloroacetic acid(3) 0.1 M fluoroacetic acid (4) 0.1 M difluoroacetic acid

The electrical conductivity of an aqueous solution is determined by the concentration of ions in the solution. The more ions a substance can produce when dissolved in water, the higher its conductivity.

1. Acetic acid (CH3COOH) is a weak acid and only partially ionizes in water. Therefore, a 0.1 M solution of acetic acid will have relatively low conductivity.

2. Chloroacetic acid (ClCH2COOH) is a stronger acid than acetic acid because the electronegative chlorine atom pulls electron density away from the acidic hydrogen, making it easier to ionize. Therefore, a 0.1 M solution of chloroacetic acid will have higher conductivity than a 0.1 M solution of acetic acid.

3. Fluoroacetic acid (FCH2COOH) is even stronger than chloroacetic acid because fluorine is more electronegative than chlorine. Therefore, a 0.1 M solution of fluoroacetic acid will have higher conductivity than a 0.1 M solution of chloroacetic acid.

4. Difluoroacetic acid (F2CHCOOH) is stronger than fluoroacetic acid because it has two electronegative fluorine atoms that can pull electron density away from the acidic hydrogen. Therefore, a 0.1 M solution of difluoroacetic acid will have the highest conductivity of the four solutions.

So, the highest electrical conductivity of the following aqueous solutions is of 0.1 M difluoroacetic acid.

The electrical conductivity of an aqueous solution is determined by the concentration of ions in the solution. The more ions a substance can produce when dissolved in water, the higher its conductivity.

1. Acetic acid (CH3COOH) is a weak acid and only partially ionizes in water, producing CH3COO- and H+ ions.

2. Chloroacetic acid (ClCH2COOH) is a stronger acid than acetic acid due to the electron-withdrawing effect of the chlorine atom, which makes the acid more likely to donate a proton (H+). Therefore, it will ionize more completely than acetic acid, producing more ions and thus having a higher conductivity.

3. Fluoroacetic acid (FCH2COOH) is even stronger than chloroacetic acid due to the electron-withdrawing effect of the fluorine atom, which is more electronegative than chlorine. This makes the acid more likely to donate a proton, so it will ionize more completely, producing more ions and thus having a higher conductivity.

4. Difluoroacetic acid (F2CHCOOH) has two fluorine atoms, which increases the electron-withdrawing effect even more, making the acid even more likely to donate a proton. Therefore, it will ionize most completely of all, producing the most ions and thus having the highest conductivity.

So, the highest electrical conductivity among the given aqueous solutions is of 0.1 M difluoroacetic acid.
