- $H_3C ? (CH_2)_3 ? OH$
- $(CH_3)_2CH ? CH_2OH$
- $(CH_3)_3C ? OH$
- $H_3C ? CH(OH) CH_2 ? CH_3$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Secondary alcohol, on reaction with anhydrous $ZnCl _{2}$ and conc. $HCl$ (Lucas reagent) gives an oily layer product after five minuts.
$H_{3}C -\underset{\overset{|}{OH}}{CH} - CH_{2}CH_{3} {->[{\text{Lucas reagent}}]}$ oily layer
product (turbidity) after 5 min.
$H_{3}C -\underset{\overset{|}{OH}}{CH} - CH_{2}CH_{3} {->[{\text{Lucas reagent}}]}$ oily layer
product (turbidity) after 5 min.

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.
