Reaction (d) is a termination step in halogenation. This step stops the consumption of reactants and/or chain is terminated as free radicals are consumed.

Q. Which of the following is a termination step in halogenation?

$Cl - Cl h v C ∙ l + C ∙ l$

$C H_{4} + Cl h v C ∙ H_{3} + H Cl$

$C H_{3} Cl + C ∙ l ⟶ C ∙ H_{2} Cl + H Cl$

$H_{3} C ∙ + C ∙ l ⟶ C H_{3} Cl$

Reaction (d) is a termination step in halogenation. This step stops the consumption of reactants and/or chain is terminated as free radicals are consumed.

Q. Which of the following is a termination step in halogenation?

Cl−Clhv​C∙l+C∙l

CH4​+Clhv​C∙H3​+HCl

CH3​Cl+C∙l⟶C∙H2​Cl+HCl

H3​C∙+C∙l⟶CH3​Cl

Reaction (d) is a termination step in halogenation. This step stops the consumption of reactants and/or chain is terminated as free radicals are consumed.

$Cl - Cl h v C ∙ l + C ∙ l$

$C H_{4} + Cl h v C ∙ H_{3} + H Cl$

$C H_{3} Cl + C ∙ l ⟶ C ∙ H_{2} Cl + H Cl$

$H_{3} C ∙ + C ∙ l ⟶ C H_{3} Cl$
