The following method can be considered suitable for the preparation of alkyl halide:

Correct answer: B. ROH and PX3

  • A. Halogenation of alkane
  • B. ROH and PX3
  • C. ROH and HX
  • D. Alkene and HX

Explanation

Option B is correct.ROH and PX3 is not a suitable method for the preparation of alkyl halide. In this method, an alcohol is reacted with a phosphorus halide, such as phosphorus trichloride (PX3). The phosphorus halide reacts with the hydroxyl group of the alcohol molecule, forming a phosphate ester. A phosphate ester is not 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.
