The compound which does not respond to iodoform test is
Options
- ACH 3 - CHO
- BCH 3 CH OH CH 3
- CC 2 H 5 - CO - C 2 H 5
- DC 6 H 5 COCH 3
Correct answer
C. C 2 H 5 - CO - C 2 H 5
Step-by-step solution
Iodoform test is given compounds have either CH 3 - CO - group or CH 3 - CHOH - group. The reagents of the iodoform test: 1   I 2 + NaOH 2   I 2 + OH - 3   NaOI Thus, CH 3 - CHO , CH 3 - CH OH - CH 3 and C 6 H 5 COCH 3 give positive iodoform when warmed with I 2 + NaOH and C 2 H 5 - CO - C 2 H 5 does not respond to the iodoform test.
