Question

Define 3 Types of Isomerism with there example?​

Answer 1

Answer:

In chain isomerism, isomers differ in the arrangement of the carbon chains, that may be branched or straight. An example is the compound with the molecular formula C5H12, of which there are three isomers: n-pentane, 2-methylbutane or isopentane and 2,2-dimethylpropane or neopentane.

Answer 2

Answer:

In positional isomerism, also called position isomerism, isomers have the same functional groups but in different positions on the same carbon chain. An example is the compound with molecular formula C6H4Br2, of which there are three isomers:

Example: 1,2-dibromobenzene, 1,3-dibromobenzene and 1,4-dibromobenzene.
