Q. The number of compounds that give positive iodoform test among the following are

$( CH )_3- CH ( OH )-( CH )_3 ; CH _3- \overset{\underset{||}{O}}{C} - CH _3$
$CH _3- CH _2- CHO ; CH _3- CH _2- OH$
$CH _3- CH _2- \overset{\underset{||}{O}}{C} - CH _2- CH _3 ; CH _3- CHO$

Solution:

Compounds containing $CH_{3}-CO-$ group give iodoform test. In addition to this, ethanol and
alcohols having formula
$H_{3}C-CH\left(\right.OH\left.\right)-R$ give positive iodoform test.
