Question

In a chemical experiment, 1, 1, 2, 2- tetrabromoethane is treated with alcoholic zinc to produce an unsaturated substituted hydrocarbon.

This process represents an example of
Question 8 options:

substitution reaction

addition reaction

elimination reaction

combustion reaction

oxidation reaction

Answer 1

Elimination reaction.

Explanation: Alcoholic zinc removes halogen atoms (dehalogenation) from 1,1,2,2-tetrabromoethane, causing loss of substituents and formation of a C=C/C≡C (unsaturated) bond — a characteristic elimination process.
