Question

Which of the following does not answer iodoform test?

• A. $n$-Butyl alcohol
• B. $sec$-Butyl alcohol
• C. Acetophenone
• D. Acetaldehyde

Answer 1

Answer: (A)

Iodoform test is given by the compounds containing $C{H}_{3}CO-$ group or $C{H}_{3}CHOH$ group.
$n$ butyl alcohol $\left(C{H}_{3}C{H}_{2}C{H}_{2}C{H}_{2}OH\right)$ does not give iodoform test because it does not possess the $C{H}_{3}CO-$ or $C{H}_{3}CHOH$ group.
