Would cyclopentanone give a positive in the iodoform test? Explain.
Would cyclopentanone give a positive in the iodoform test? Explain.
Homework Answers
Ans: No,
Cyclopentanone can not give iodoform test.
for iodoform test -CH3 group should directly attached to the carbonyl group.Since cyclopentanone dont have direct -CH3 link to ketone thus it dont give iodoform test.
