Which one of the following is not an Alkyl halide?

Correct answer: C. 2-butene

  • A. 2-chloropropane
  • B. 1-chlorobutane
  • C. 2-butene
  • D. 4-chlorohexane

Explanation

Monohaloalkanes are usually called alkyl halides. The functional group of alkyl halides is halogen. They are represented by R-X.OPTION A: 2-chloropropane is an alkyl halide because it contains halogen which is chlorine.OPTION B: 1-chlorobutane is also an alkyl halide.OPTION C: 2-butene has an alkene group only. Hence, C is the correct option.OPTION D: 4-chlorohexane is an alkyl halide.

About Alkyl Halides

Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
