Which reagent is used to convert an alcohol into an alkyl halide? (2022)
Step 1: Identify the starting material, which is an alcohol. An alcohol is a compound that contains an -OH (hydroxyl) group.
Step 2: Determine the desired product, which is an alkyl halide. An alkyl halide is a compound that contains a halogen (like Cl, Br, or I) instead of the -OH group.
Step 3: Choose the reagent needed for the conversion. PCl5 (phosphorus pentachloride) is commonly used for this purpose.
Step 4: Understand the reaction process. When PCl5 is added to the alcohol, it reacts with the -OH group, replacing it with a chlorine atom, thus forming the alkyl halide.
Step 5: Conclude that PCl5 is the reagent that effectively converts alcohols into alkyl halides through a substitution reaction.
