Propylene glycol and trimethylene glycol are:
Correct answer: C. Position isomers
- A. Functional group isomers
- B. Metamers
- C. Position isomers
- D. Tautomers
Explanation
Propylene glycol and trimethylene glycol are positional isomers. In positional isomers, the same molecular formula is retained, but the functional groups or substituents are attached at different positions on the carbon chain. Both of these compounds are diols (containing two hydroxyl groups), but the positioning of the hydroxyl groups differs, which gives them distinct properties.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
