Question

What are the structures of the isomers of dichloropropane?

Answer 1

When the substituent atoms are placed on different carbon atoms in the chain, then we get different isomers. Dichloropropane means there is a chain of three carbon atoms and any two hydrogen atoms are replaced with chlorine atoms.

Complete answer:
To write the isomers of the compound, we have to change the positions of the substituent on the main chain of carbon atoms. The given compound in the question is Dichloropropane. . Dichloropropane means there is a chain of three carbon atoms and any two hydrogen atoms are replaced with chlorine atoms. So, when the positions of the chlorine atoms are changed then we get the isomers of Dichloropropane.
When the chlorine atoms are present on the first carbon atom and second carbon atom, then its name will be 1, 2-Dichloropropane. The structure is given below:

When the chlorine atoms are present on the first carbon atom and third carbon atom, then its name will be 1, 3-Dichloropropane. The structure is given below:

When both the chlorine atoms are present on the first carbon atom, then its name will be 1, 1-Dichloropropane. The structure is given below:

When both the chlorine atoms are present on the second carbon atom, then its name will be 2, 2-Dichloropropane. The structure is given below:

So, there are four isomers of Dichloropropane.

Note:
All the isomers given above are positional isomers, other isomers are structural isomers, chain isomers, functional isomers, metamerism, tautomerism, ring-chain isomerism, stereoisomerism, etc.
