Text Solution

Verified by Experts

The correct Answer is:
D
`CH_(3)CH_(2)CH_(2)CH(OH)CH_(3)overset([O])rarr underset("Keto methyl group")(CH_(3)CH_(2)CH_(2)COCH_(3))`
`underset("Keto methyl group")(CH_(3)CH_(2)CH_(2)overset(O)overset(||)C-CH_(3))+3l_(2)+4NaOH rarr`
`CH_(3)CH_(2)CH_(2)overset(O)overset(||)C-overset(-)Ooverset(+)Na+underset("yellow (ppt)")underset("Iodoform")(CHl_(3))+3H_(2)O+"3 Nal"`
