Q. A compound that shows positive iodoform test is

KVPYKVPY 2011

Solution:

Iodoform test with sodium hypoiodite is used for the detection of $CH _{3} CO$ group or $CH _{3} CH ( OH )$ group which produces $CH _{3} CO$ group on oxidation.
Iodoform reaction with the given compounds are as follows :

If gives positive iodoform test due to the presence of $CH _{3} CO$ group.

It gives negative iodoform test.

It doesn't give positive iodoform test.
(d) $\underset{\text{1 - pentanol}}{CH_3CH_2CH_2CH_2CH_2OH} + I_2/NaOH$
$\xrightarrow{H^+/H_2O} $ no reaction
It also gives negative iodoform test.
