Organic synthesis. Pear-shaped flask being heated with a bunsen burner during synthesis of bromobutane. This is a substitution reaction, where butanol is reacted with hydrogen bromide to form a halogenoalkane (1-bromobutane). The reaction is very volatile and needs to go to completion, so reflux is utilized. A condensing tube (down centre) that is cooled by cold flowing water (pipes, orange) returns evaporated reactants to the flask.
