Question

Which of the following will give a negative test when treated with bromine in carbon tetrachloride?
Options
A Butane
Correct Answer
B 2-Butene
C 1,3-Butadiene
D 2-Butyne
Correct Answer

Option A is the correct answer.

Detailed Explanation

Bromine in CCl4 tests for unsaturation. Butane is an alkane (saturated hydrocarbon) and will not react with bromine in CCl4, giving a negative test (no decolorization). Alkenes (2-butene, 1,3-butadiene) and alkynes (2-butyne) will decolorize the bromine solution.

Hint

Which compound is saturated?
