Most common reactions shown by alkyl halides are:
Correct answer: A. Substitution
- A. Substitution
- B. Elimination
- C. Reduction
- D. Polymerization
Explanation
Alkyl halides, also known as haloalkanes, commonly undergo substitution reactions. The halogen atom in the alkyl halide can be replaced by a nucleophile in substitution reactions. There are two main types of substitution reactions involving alkyl halides. In these reactions, a nucleophile replaces the leaving group. SN1 reactions proceed via a two-step mechanism with the formation of a carbocation intermediate, while SN2 reactions involve a single concerted step with direct substitution.

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.
