What are structural isomers ? List any four characteristics of isomers. Draw the possible structures of butane.
Structural Isomers-
Compoundds which have same molecular formula but different structure are called structural isomers.
Characteristics of Isomers -
(i) They have same molecular formula but their structures are different.
(ii) They have different physical properties.
(iii) They have same number of atoms.
(iv) Isomers may have same or different chemical properties.
