... Making a Halogenoalkane Aim The aim of this activity is to prepare a sample of 1-bromobutane, an example of a halogenoalkane. This activity will involve learning how to use new techniques and equipment, firstly to carry out the reaction and form the product, and secondly to separate and purify the halogenoalkane. I will attempt to obtain the maximum yield possible of 1-bromobutane. I shall examine the product that I have obtained and comment on the amount. I shall also evaluate any practical difficulties I experience in obtaining the halogenoalkane. Background Information The overall process involved in making a halogenoalkane is simply to replace the -OH group in an alcohol by a halogen atom. The actual process to produce a halogenoalkane is slightly more complex, involving more than one single reaction. Butan-1-ol is heated in a mixture of concentrated sulphuric acid and sodium bromide. There are two main reactions. Firstly, the sulphuric acid reacts with the sodium
