Reduction of alkyl halides in the presence of Zn and mineral acid produces _ ?
Correct answer: B. Alkane
- A. Alkenes
- B. Alkane
- C. Alkynes
- D. Alcohols
Explanation
Option B is correct as zinc carries out reductive dehalogenation of "alkyl halides" in which the halogen atom is replaced by a hydrogen atom in the presence of proton donors such as carboxylic acids.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
