Question

Which of the above compounds on being warmed with iodine solution and NaOH will give iodoform?

• A. (i), (ii) and (iv)
• B. Only (ii)
• C. (i), (ii) and (iii)
• D. (i) and (ii)

Hint:

The iodoform test is positive for compounds with a methyl group directly bonded to a carbonyl group (CH3-CO-).

Answer 1

The Correct Option is A

Iodoform reaction occurs with compounds that have a methyl group adjacent to a carbonyl group. The compounds in (i), (ii), and (iv) will give iodoform on reaction with iodine and NaOH.

Step 2: Conclusion.
The compounds that will give iodoform are (i), (ii), and (iv), corresponding to option (a).
