A. Functional Group Isomers
B. Metamers
C. Position Isomers
D. Tautomers


Correct Answer: B. Metamers

Detail about MCQs

Metamers are a type of constitutional isomerism where the connectivity of atoms in the molecules is the same, but the arrangement of atoms along the carbon chain differs. Propylene glycol and trimethylene glycol have the same molecular formula (C3H8O2), but the arrangement of carbon atoms differs, leading to different chemical properties.
