Question
Which of the following compounds does not give iodoform test on treatment with I2/NaOH?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Butanone (CH3CH2COCH3) does not give a positive iodoform test because it does not have the CH3CO- group. Ethanol (oxidized to acetaldehyde), propanone (acetone), and 2-propanol (oxidized to acetone) all have the CH3CO- or CH3CHOH- group and give positive tests.
Hint
Which ketone lacks the CH3CO- group?
