Among the following, the compounds which gives iodoform reaction with `I_2 & NaOH `is `CH_3 CHO ,CH_2CH_2 OH ,C_6 H_5 CHO ,C_6 H_5 COCH_3 ,CICH_2 CHO ,ICH_2CHO ,CH_3 CH_2 CH_2 CHO ,CH_3 CH_3 COCH_3`

Text Solution

Verified by Experts

The correct Answer is:
5
Which give iodoform reaction are carbinal of carbon atom bonded to methyl group `alpha ` -hydrogen atom are (presence of acyl group
`CH_3 - overset(O ) overset(||)C-`
`CH_3 - overset(O ) overset(||)C -H ✔,CH_3-CH_2-OH ✔ ,C_6 H_5 - overset(O) overset(||)C -H xx ,C_6 H_5 -CO- CH_3 ✔ ,CI -CH_2 - overset(O) overset(||)C -H xx ,I-CH_2-CHO ✔, Pr-CHO xx , CH_3 CH_2 COCH_3 ✔.`
