Why does butane show isomerism?
Answer and explanation
Correct answer: Because a four-carbon chain can be straight or branched
Butane has the molecular formula C₄H₁₀. Its four carbon atoms can form a continuous straight chain in n-butane or a three-carbon chain with a methyl branch in 2-methylpropane (isobutane). Both structures contain four carbon and ten hydrogen atoms, but their connectivity differs, so they are structural isomers. The other options incorrectly describe its composition or bonding.
