In this video, we're going to take a look at alcohol reactions dealing with substitution. Now we're going to say under these substitution reactions, hydrochloric acid or hydrobromic acid react with an alcohol. Here, our hydrochloric acid changes Oh into Cl, and our hydrobromic acid changes Oh into Br. If we take a look here at this example reaction, we have our alcohol as our starting material, and we're reacting it with one of these two acids. X here represents either CL or BR. So all that happens here is that our o h group gets changed into one of the halogens of this acid. And the result is we go from having an alcohol to having an alkyl halide. Carbon is no longer connected to an Oh group, but instead it's going to be connected to a halogen in the form of chlorine or bromine. So just remember that, you have an alcohol, use HCL to change it into CL, or use HBR to change it into BR.

Determine the alkyl halide formed in the following reaction. So here, we're starting out with our alcohol, and this would be 1 propanol. We're gonna react it with hydrobromic acid. Remember, Hydrobromic acid will convert the Oh group into a b r. So now it becomes CH3CH2 c h 2 b r. You go from 1 propanol to 1 bromo propane. So here we've gone from an alcohol to an alkyl halide, and this would be our final answer.
