प्रश्न
Explain why propane cannot exhibit the structural isomerism property.
उत्तर
Propane has the chemical formula C3H8 and it is represented as CH3-CH2-CH3. In alkanes, isomerism arises when a particular compound can be represented in the form of both straight chain and branched chain. Also, the branching cannot be done from the first or the last carbon atom of the structure.
The structural formulae of propane show that they do not have the sufficient number of carbon atoms to exist in the form of branched isomer. Hence, they do not exhibit structural isomerism
