Which of the following statements is true for the halogenation of alkanes carried out as shown below

Options

  1. AThe ratio of products [A] /[B] is greater for X=B r as compared to X=C l .
  2. BThe ratio of products [ A / /[ B ] is lower for X = Br as compared to X = Cl .
  3. CThe reaction has an early transition state for X = Cl and a late transition state for X = Br
  4. DThe reaction has a late transition state for X = Cl and an early transition state for X = Br .

Correct answer

C. The reaction has an early transition state for X = Cl and a late transition state for X = Br

Step-by-step solution

i is more reactive and less selective B r ₁ is more selective and les, reactive
