Reduction of alkyl halides in the presence of Zn and mineral acid produces _.
Correct answer: B. Alkanes
- A. Alkenes
- B. Alkanes
- C. Alkynes
- D. Alcohols
Explanation
Alkyl halides (except fluorides) on reduction with zinc dilute hydrochloric acid give alkanes:Zn +H2 → ZnH2ZnH2 + 2CH3Cl → ZnCl2 +2CH4

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.
