CH 3 CHO and all other ketones containing COCH 3 group give iodoform test. Butanol-2 on oxidation with CrO 3 gives ethylmethyl ketone, which gives iodoform test positive. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/6a9116ad7eea83e8ca93a617599c0d75-.png" />

Q. Which of the following on oxidation with $C r O_{3}$ would give a product that would give iodoform test?

Butanol-2

Methanol

t-butanol

None of these

$C H_{3} C H O$ and all other ketones containing $COC H_{3}$ group give iodoform test. Butanol-2 on oxidation with $C r O_{3}$ gives ethylmethyl ketone, which gives iodoform test positive.
