What type of reaction occurs when an alcohol is converted to an alkyl halide using phosphorus tribromide (PBr3)?

Step 1: Identify the starting material, which is an alcohol. An alcohol has a hydroxyl group (-OH).
Step 2: Recognize the reagent being used, which is phosphorus tribromide (PBr3).
Step 3: Understand that in this reaction, the hydroxyl group (-OH) of the alcohol will be replaced.
Step 4: Know that the bromine atom from PBr3 will take the place of the hydroxyl group.
Step 5: Conclude that this process is called a substitution reaction because one group (the hydroxyl) is substituted by another group (the bromine).
