Chemistry of Carboxylic Acids

Question 1

Carboxylic Acids are acidic due to two reasons:

Answer 1

They have a polar effect with the carbonyl carbon vs. oxygen, and they also are resonance stabilized.

Question 2

You can increase acidity by adding :

Answer 2

halides. for example, trifluoroacetic acid.

Question 3

Which are more acidic? Sulfonic acids, or carboxylic acids?

Answer 3

Sulfonic acids because sulfur oxidation state can better stabilize negative charge on oxygens.
