Question

Explain isomerism. State any four characteristics of isomers. Draw the structures of possible isomers of butane, C₄H₁₀.

Answer 1

 Isomerism is a phenomenon due to which some compounds have same molecular formula but different structural formulae. 

Characteristics: 

(i) They differ in structural formula. 

(ii) They differ in melting point. 

(iii) They differ in boiling point. 

(iv) They differ in solubility in same solvent.

There are two isomers of butane,C₄H₁₀
