CAIE A Level Chemistry 9701 · An introduction to organic chemistry
A student carries out two separate organic reactions.
Reaction 1: An excess of methylamine, , is added to a solution of chloroethane, , in ethanol at room temperature.
Reaction 2: Ethene gas, , is bubbled through a solution of bromine in tetrachloromethane at room temperature.
Compare these two reactions in terms of the type of reaction, the type of bond fission, the nature of the attacking species, and the change in saturation of the organic molecules involved.
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Compare means: Give similarities or differences between two things, and say which side each point belongs to. Write each point as a pair, for example: A is X, whereas B is Y. Two separate descriptions rarely earn the marks.
