In the distillation process, what is the importance of continuous flow of water in the condenser?
Why is it also necessary that the concentrated HCl to be used is cold ?
(this is for the synthesis of an alkyl halide.)
Answer:
When distilling you are basically evaporating the liquid to a pure gaseous form and with the cold water you are condensing it back into a liquid. If the water is not on then you would evaporate all of your sample.
When synthesizing an alkyl halide the reaction gets hot to begin with. If the HCl is not cold then the reaction mixture will get so hot you will decompose your sample
If water doesn't flow enough it won't stay cold and your gas won't condense is the obvious answer.
The purpose of the condenser, as the name implies, is to condese vapor into a liquid form such that it can be differentially collected based on its boiling point. It is wise to keep the HCl cold due to the fact that reactions with an acid or base generally result in a large amount of heat (that is, they are exothermic). To counteract this heat, the reagent is added cold as not to promote unwanted side reactions that are a result of the heat.
