Vicinal dihalides on treatment with Zn-dust give:
Correct answer: A. Alkenes
- A. Alkenes
- B. Alkynes
- C. Alkanes
- D. All of them
Explanation
Vicinal dihalides have two halogens on adjacent carbon atoms. Dehalogenation occurs when dihalide is treated with Zinc dust in an anhydrous solvent like methanol or acetic acid.CH2CHX2 or XH2C−CH2X+Zn dust→CH2=CH2

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.
