# How do you find optical isomers?

You will have to refine this question. I cannot ascertain what you are trying to learn. In organic chemistry any carbon atom that is bound to 4 different substituents, i.e. $C {R}_{1} {R}_{2} {R}_{3} {R}_{4}$ will generate 2 optical isomers that are not superposable. Anyway, it's over to you.
