Question: Which of the following statements about carboxylic acids is incorrect? (2020)

Options:

  1. They can form hydrogen bonds.
  2. They have higher boiling points than alcohols.
  3. They are less acidic than alcohols.
  4. They can be converted to esters.

Correct Answer: They are less acidic than alcohols.

Exam Year: 2020

Solution: 

Carboxylic acids are more acidic than alcohols due to the resonance stabilization of their conjugate base, making the statement \'They are less acidic than alcohols\' incorrect.

  4. They can be converted to esters.

Questions & Step-by-Step Solutions

Which of the following statements about carboxylic acids is incorrect? (2020)
  • Step 1: Understand what carboxylic acids are. They are organic compounds that contain a carboxyl group (-COOH).
  • Step 2: Know that acidity refers to how easily a substance can donate a proton (H+).
  • Step 3: Compare carboxylic acids to alcohols. Alcohols have a hydroxyl group (-OH) and are less acidic than carboxylic acids.
  • Step 4: Learn about resonance stabilization. Carboxylic acids can stabilize their conjugate base (the part left after donating a proton) through resonance, making them more acidic.
  • Step 5: Identify the incorrect statement. The statement 'They are less acidic than alcohols' is wrong because carboxylic acids are actually more acidic.
