alleryThe phenomenon in which compounds have the same molecular formula but different structural formulae is called:
AFunctional isomerism
BGeometrical isomerism
CStructural isomerism
DChain polymerisation
Answer & Solution
Correct answer: C. Structural isomerism
1. The molecular formula C4H10 can be drawn as a straight chain or a branched chain.
2. These are different compounds because their structural formulae differ.
3. Same molecular formula but different structures is named structural isomerism.
