Which of the following statement is true regarding the reactivity order in order to form alkyl halides

Correct answer: C. Hydrogen Bromide is less than that of hydrogen iodide

  • A. Hydrogen iodide is less than that of hydrogen Bromide
  • B. Hydrogen Bromide is less than that of HCL
  • C. Hydrogen Bromide is less than that of hydrogen iodide
  • D. HCL is greater than that of hydrogen iodide

Explanation

Hydrogen Bromide is less reactive than hydrogen iodide when it comes to forming alkyl halides. The reactivity order for forming alkyl halides follows the trend Iodine > Bromine > Chlorine. This is because larger halogens (iodine) have weaker bond strengths and are more polarizable, making them more susceptible to nucleophilic attack by alkyl groups. Option A and B are incorrect as they do not follow the correct reactivity trend. Option D is incorrect as HCl is not more reactive than hydrogen iodide for alkyl halide formation.
