Q78 / 160 · JIPMER 2005 · Chemistry
Which of the following compound gives iodoform test?
- A$\mathrm{CH}_3 \mathrm{CN}$
- B$\mathrm{CH}_3 \mathrm{OH}$
- Correct answerC$\mathrm{CH}_3 \mathrm{COCH}_3$
- D$\mathrm{C}_6 \mathrm{H}_5 \mathrm{OH}$
Solution
Compounds containing \(\left(\begin{array}{ll} \quad \quad \quad \mathrm{O} \\ \qquad \quad ~||\\ \mathrm{CH}_3-\mathrm{C}- \\ \\ \end{array}\right)\)
group give the iodoform test.
$\mathrm{CH}_3-\mathrm{C}-\mathrm{O}-\mathrm{CH}_3+3 \mathrm{I}_2+\mathrm{NaOH} \longrightarrow \mathrm{CHI}_3+\mathrm{HCOONa}+\mathrm{H}_2 \mathrm{O}$
