Optical isomerism is a kind of streoisomerism in which isomers differ in their behaviour towards plane polarised light, What are enantiomers?

Optical isomerism is a kind of streoisomerism in which isomers differ in their behaviour towards plane polarised light, What is the cause of optical activity in organic compounds?

Optical isomerism is a kind of streoisomerism in which isomers differ in their behaviour towards plane polarised light,Write the structure of the isomers of C_4H_9Cl which is optically active.

What is plane polarised light?

The prefixes 'erythro' and 'threo' are used for distinguishing a pair of enantiomers containing two chiral carbon atoms when two of the atoms or groups on each chiral carbon atom are the same while the third is different. The stereoisomer, in which the two identical groups are on the same side of the Fischer projection formula, is called the erythro isomer while the isomer, in which the two identical groups are on the opposite sides of the Fischer projection formula, is called the threo isomer. Erythro isomer among the following is :
