Question

Define isomerism. Draw all possible isomers of butane?

Answer 1

Isomerism:

• When two or more organic compounds have the same molecular formula but different structural formula, then the compounds are called isomers, and this phenomenon is called isomerism.
• Chemical compounds that have identical chemical formulae but differ in properties and the arrangement of atoms in the molecule are called isomers.

Butane(C₄ H₁₀ ) shows two types of isomerism:

• n-butane
• Iso butane
