Which of the following ketones will not respond to iodoform test?

AMethyl isopropyl ketone
BEthyl isopropyl ketone
Correct Answer
CDimethyl ketone
D$$2$$-hexanone

Solution

Ethyl isopropyl ketone will not respond to iodoform test as it lacks methyl keto group ($$ \displaystyle CH_3- \underset { \displaystyle { \underset { \displaystyle \text { O } }{ || } } }{C }-$$ group ) .
All the ketones except ethyl isopropyl ketone gives iodoform test as they contain methyl keto group.
