Questions: All six compounds are acids. Select the statements that are true. (A) H-Cl (B) H-F A and B are binary acids. C and D are carboxylic acids. E and F are carboxylic acids. B is a stronger acid than A because the fluorine atom is more electronegative than the chlorine atom. C is a stronger acid than D because there are more oxygen atoms surrounding the central atom in C than in D. The presence of the chlorine atom in F makes it a stronger acid than E.

Transcript text: All six compounds are acids. Select the statements that are true. (A) $\mathrm{H}-\mathrm{Cl}$ (B) $\mathrm{H}-\mathrm{F}$ A and $B$ are binary acids. C and D are carboxylic acids. $E$ and $F$ are carboxylic acids. B is a stronger acid than A because the fluorine atom is more electronegative than the chlorine atom. C is a stronger acid than D because there are more oxygen atoms surrounding the central atom in C than in D. The presence of the chlorine atom in F makes it a stronger acid than E.

Solution

Solution Steps

Step 1: Identify Binary Acids

A and B are binary acids because they consist of hydrogen and one other element (HCl and HF).

Step 2: Identify Carboxylic Acids

C and D are not carboxylic acids; they are oxyacids (H₂SO₄ and H₂SO₃).
E and F are carboxylic acids because they contain the -COOH group (CH₃COOH and ClCH₂COOH).

Step 3: Compare Acid Strength Based on Electronegativity

B (HF) is a stronger acid than A (HCl) because fluorine is more electronegative than chlorine, making HF more likely to donate a proton.

Final Answer

A and B are binary acids.
E and F are carboxylic acids.
B is a stronger acid than A because the fluorine atom is more electronegative than the chlorine atom.
