Compounds having same molecular formula but differ in structural formula are called __________________?
Correct answer: C. isomer
- A. polymer
- B. monomer
- C. isomer
- D. allotropes
Explanation
Isomers have the same molecular formula but different arrangements of atoms or different spatial arrangements. When the structural formula differs, they are structural or constitutional isomers. The likely mistake is polymer, which means a large molecule made from repeating monomer units and does not describe compounds with the same molecular formula.

About Isomerism
Isomerism occurs when compounds have the same molecular formula but different atom arrangements or spatial orientations. The content includes chain, position, functional, metameric and tautomeric isomerism, along with geometrical and optical isomerism, including cis-trans forms, E/Z notation, chirality and enantiomers.
