The amine produced in the above reaction (2-amino-pentane) forms a mixture of two optical isomers.

i) Draw the 3D structures of the two isomers of the amine product that you named and produced a drawing of in part a ii).

ii) With reference to a different named example, explain the term optical isomer. You should draw the 3D structure of the example considered.

iii)Describe (with reference to the equipment used) how you can distinguish between the mixture of two optical isomers of this amine
