The correct order of the addition reaction rates of halogen acids with ethylene is
- A hydrogen chloride \(>\) hydrogen bromide > hydrogen iodide
- B hydrogen iodide \(>\) hydrogen bromide > hydrogen chloride
- C hydrogen bromide \(>\) hydrogen chloride > hydrogen iodide
- D hydrogen iodide \(>\) hydrogen chloride > hydrogen bromide
Answer & Solution
Correct Answer
(B) hydrogen iodide \(>\) hydrogen bromide > hydrogen chloride
Step-by-step Solution
Detailed explanation
In halogen acids, as the size of halogen atom increases, the bond between halogen and hydrogen atom weakens. Therefore, the case with which the bond can be broken increases. The correct order of the addition reaction rates of halogen acids with ethylene is hydrogen iodide (HI)…
