Which hydrogen halide is the most reactive in the addition to alkenes?

Options

  1. AHCl
  2. BHBr
  3. CHI
  4. DThey all react equally.

Correct answer

C. HI

Step-by-step solution

The order of reactivity of hydrogen halides in the addition to alkenes is HI > HBr > HCl. HI is the most reactive among them due to the larger size and higher polarizability of iodine, making it a strong electrophile in the addition reaction.
