Which of the following test can be used for distinguishing an alkane and an alkene

Correct answer: D. Both "A" and "B"

  • A. Bromine water test
  • B. Hydroxylation
  • C. Ozonolysis
  • D. Both "A" and "B"

Explanation

When differentiating between an alkane and an alkene, it is important to consider their saturation levels. Alkanes are saturated hydrocarbons, while alkenes are unsaturated. The correct answer is Option D, as both the bromine water test and hydroxylation with Baeyer's reagent can be used to distinguish between alkanes and alkenes based on their reactivity. Option A, the bromine water test, specifically reacts with alkenes to form vicinal dihalides, indicating unsaturation. Option B, hydroxylation with Baeyer's reagent, decolorizes the solution when in contact with alkenes due to the presence of unsaturation. Option C, ozonolysis, is not suited for testing saturation presence, but rather for locating the position of double bonds in compounds.

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.
