Our leaving group is the alcohol group, we’re replacing it with the halide bromine. Nucleophile is the bromide ion. In the reaction, the source of it is NaBr. We can’t simply just add it and it will leave because the hydroxide is a poor leaving group. We have to change the leaving group by protonating it with sulfuric acid. The leaving group then becomes a water molecule and will definitely replace when the bromide molecule attacks. The experiment is being run at half scale. We will be using sulfuric acid, and we must be very careful with it. You will know immediately about it. In the beginning of the reaction, add the acid slowly, it’s an exothermic process, you don’t want to add it quickly. More importantly, it may char the solution because of intense heat, but you may get a lower product, but the reaction should still take place. Another thing that may happen is the solution turning reddish or orangish. What is happening is the bromine is getting oxidized by chlorine by accidentally adding tap water. Also, washing the test tubes may have caused this, but there is not much difference in the reaction. This is set up as a distillation, but the product cleanup, the way we will do it, is much simpler. We change it up because it will end up
