Question

which reaction should be used to convert propene into an alkyl halide?
addition
condensation
elimination
substitution

Explanation:

Propene is an unsaturated hydrocarbon with a double - bond. In an addition reaction, a molecule adds across the double - bond of propene. When a hydrogen halide (HX) is added to propene, the hydrogen and halogen atoms add across the double - bond, forming an alkyl halide. Condensation reactions involve the combination of two molecules with the elimination of a small molecule like water. Elimination reactions remove atoms or groups from a molecule to form a double or triple bond. Substitution reactions replace one atom or group in a molecule with another.

Answer:

A. addition
