Compounds having the same molecular formula, same structure with different configuration are called stereoisomers and the phenomenon is called stereoisomerism. The phenomenon is broadly classified with three types called (a) geometrical isomerism (b) optical isomerism and (c) conformational isomerism. Which of the following compounds exhibit both geometrical as well as optical isomerism

Carbon compounds with identical molecular formula but different structural formulae are called
