The process of converting alkyl halides to alcohols involve

Explanation:

Reaction with Alkyl halides -

Alkyl halides goes for two reactions - Substitution and elimination reaction.

In substitution reaction the X group in R-X is replaced by different group i.e.

R-X → R-OH + X⁺

In elimination reaction, the elements of H-X are eliminated from R-X; the product is very often alkene.

Hence the correct option is Substitution.

Additional Information

Addition Reaction:

• It occurs when two reactants combine to form a single new product with no atoms left over.
• In addition reaction, new group X and Y are added to the starting material.
• A π bond is broken and two σ bond are formed.
