An alkyl halide reacts with aqueous KOH solution to give an:

C. Alcohol

The reaction of an alkyl halide with aqueous KOH solution typically results in the formation of an alcohol.

Here’s why:

• Alkyl halide: This represents a molecule where a halogen atom (Cl, Br, I, or F) is bonded to an alkyl group (a hydrocarbon chain).
• Aqueous KOH solution: This refers to potassium hydroxide (KOH) dissolved in water. KOH acts as a strong base, with the OH⁻ ion being the nucleophile (electron-rich species) that attacks the alkyl halide.

In the reaction, the nucleophilic OH⁻ ion attacks the carbon atom bonded to the halogen in the alkyl halide. The halogen atom leaves as a halide ion (Cl⁻, Br⁻, I⁻, or F⁻), and a new C-O bond is formed, creating an alcohol.

Therefore, the answer is:

C. Alcohol
