Answer:The correct answer is Addition reaction.
Step-by-step explanation:
Addition reaction; The reaction in which one molecule combines with smaller molecule to give a single. When propene is converted into an alkyl halide addition reaction will take place.
Where as in condensation reaction two larger molecule fuse together with release of smaller molecules.
In Elimination reaction in which sum molecules are eliminated from the compounds.
in substitution reaction , is same as of single displacement reaction.
