Explain the followings with an example :
Position isomerism .

Explanation

Position isomerism : The compounds having same molecular formula but differ with respect to the position of multiple bonds (double or triple bonds), substituents or functional groups are called position isomers. This phenomenon is known as position isomerism. For example,
`underset("Propan-I-ol")(CH_3-CH_2-CH_2-OH) " " underset("Propan - 2- ol")underset(OH)underset(|)(CH_3-CH-CH_3)`
