Which one among the following alcohols will give iodoform on treatment with iodine and sodium hydroxide?
Updated On: Nov 24, 2023
- $C_{6}H_{5}-\underset{\overset{|}{OH}}{C}H-C_{6}H_{5}$
- $H_{3}C-OH $
- $C_{6}H_{5}-\underset{\overset{|}{OH}}{C}H-CH_{3}$
- $H_3C-CH_{2}\underset{\overset{|}{OH}}{C}H-C_{6}H_{5}$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The compounds containing $CH_3-\overset{\underset{|||}{OH}}{C}$ and
$CH_3 -\overset{\underset{|}{OH}}{C} -H$ groups on heating with (aq) $NaOH +I_{2}$
gives iodoform test (yellow ppt of iodoform).
Therefore, the compound, $C _{6} H _{5}- \underset{\overset{|}{OH}}{C} H - CH _{3}$ gives iodoform test.
$CH_3 -\overset{\underset{|}{OH}}{C} -H$ groups on heating with (aq) $NaOH +I_{2}$
gives iodoform test (yellow ppt of iodoform).
Therefore, the compound, $C _{6} H _{5}- \underset{\overset{|}{OH}}{C} H - CH _{3}$ gives iodoform test.

Alcohols
What is Alcohol?
Alcohol is a derivative of water (H2O) that has one, two, or more hydroxyl groups that are attached to a carbon atom of a hydrocarbon chain (an alkyl group). It is one of the most common organic compounds used in sweeteners, fragrances, and medicine.

Uses of Alcohol:
- Ethanol is the alcohol used in alcoholic drinks. It can be used as an industrial methylated spirit where methanol is used very little in quantity as it can be dangerous.
- It is used as fuel to produce carbon dioxide and water by the process of fermentation. Whereas methanol burns carbon dioxide and water to facilitate combustion.
- Alcohol is an organic compound used as a solvent that is insoluble in water.
- It can be used to lower the level of sugar.
- Alcohol is used as a preservative in laboratories.
