$\text{When two or more compounds differ in the position of substituent atom or functional group on the carbon skeleton, they are called position isomers. They have the same carbon skeleton and the same functional groups but differ from each other in the location of the functional groups on or in the carbon chain.}$ $\text{i. Compounds have been given in option one, the position of the Cl atom changes without changing the parent chain. Hence, it is an example of position isomerism.}$ $\text{CH}_3-\text{CH}-\text{Cl}$ $\text{and}$ $\text{CH}_2-\text{CH}_2-\text{Cl}$ $\text{with OH groups}$ $\text{The IUPAC name of the compound is 1-Chloroethanol and 2-chloroethanol}$ $\text{ii. Compounds have been given in option two, the position of NH}_2 \text{ group changes without changing the parent chain. Hence, it is an example of position isomerism.}$ $\text{CH}_3-\text{CH}_2-\text{CH}_2-\text{NH}_2$ $\text{and}$ $\text{CH}_3-\text{CH}-\text{CH}_3$ $\text{with NH}_2$ $\text{The IUPAC name of the compound is propanamine and propan-2-amine}$ $\text{iii. Compounds given in option three, the position of the double bond group changes without changing the parent chain. Hence, it is an example of position isomerism.}$ $\text{CH}_3-\text{CH}_2-\text{CH}=\text{CH}_2$ $\text{and}$ $\text{CH}_3-\text{CH}=\text{CH}-\text{CH}_3$ $\text{The IUPAC name of the compound is but-1-ene and but-2-ene.}$ $\text{iv. Compounds given in option four are not an example position isomerism because in both the compounds the parent chain is not the same.}$ $\text{CH}_3-\text{CH}_2-\text{CH}_2-\text{CH}_2-\text{CN}$ $\text{and}$ $\text{CH}_3-\text{CH}_2-\text{CH}-\text{CH}_3$ $\text{with CN}$ $\text{The IUPAC name of the compound is Pentanenitrile and 2-Methylbutanenitrile.}$
