Which of the following is a straight-chain alkyl carboxylic acid with the chemical formula CH3CH2CH2CO2H?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Butyric acid.

 

The chemical formula CH₃CH₂CH₂CO₂H represents butanoic acid (also known as butyric acid).

It is a straight-chain alkyl carboxylic acid with four carbon atoms:

  1. CH₃ - Methyl group
  2. CH₂ - Methylene group
  3. CH₂ - Another methylene group
  4. CO₂H - Carboxyl group

Thus, butanoic acid has the molecular formula C₄H₈O₂.
