Question

How are alcohols prepared from haloalkanes?

• A. By treating with concentrated H\(_2\)SO\(_4\)
• B. By heating with aqueous NaOH
• C. By treating with a strong reducing agent
• D. By treating with Mg metal

Hint:

Haloalkanes can be converted to alcohols by nucleophilic substitution with hydroxide ions from aqueous NaOH.

Answer 1

The Correct Option is B

Step 1: Understand the preparation of alcohols.
Alcohols can be prepared from haloalkanes via nucleophilic substitution reactions.
Aqueous NaOH provides the hydroxide ion (\(OH^-\)) that substitutes the halide ion, resulting in the formation of alcohols.
Step 2: Identify the correct method.
Heating haloalkanes with aqueous NaOH is the typical method to prepare alcohols, where the halide ion is replaced by the hydroxyl group.
