2-methyl propene is isomeric with butene-1. They can be distinguished by:
Correct answer: D. O3, Zn / H2O
- A. Baeyer's reagent
- B. Ammonical AgNO3
- C. Br2 solution
- D. O3, Zn / H2O
Explanation
Ozonolysis of these will give different products which can differentiate between but-1-ene and 2-methyl propene. Baeyers reagent and bromine solution are tests for unsaturation, and 2-methyl propene and butene are both unsaturated. Ammonical AgNO3 forms white precipitate with aldehydes and terminal alkynes; neither of which are present here.

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.
