Question

Compound `A,C_(8)H_(10)O`, is found to react with `NaOI` (produced by reacting `Y` with `NaOH`) and yields a yellow precipitate with characteristic smell.
`A` and `Y` are respectively
A.
B.
C.
D.

Answer 1

Correct Answer - A
Iodoform reaction with sodium hypoiodite is used for the detection of `CH_(3)CO` group. Also compounds containing `CH_(3)CH(OH)` group shows positive iodoform test as it produces `CH_(3)CO` group on oxidation.
Since, among the compounds, `CH_(3)CH(OH)` group is given only in the substrate of option (a) hence, it is correct. The reaction of compound A with NaOI is given as follows :
`2NaOH+I_(2) to NaOI+NaI+H_(2)O`
