Correct answer is (c) overset bullet C H 3+ overset bullet C H 3 longrightarrow CH 3- CH 3

Q. Which of the following reaction has zero activation energy?

$C H_{4} + Cl ∙ ⟶ C ∙ H_{3} + H Cl$

$C l_{2} ⟶ 2 Cl ∙$

$C ∙ H_{3} + C ∙ H_{3} ⟶ C H_{3} - C H_{3}$

$C ∙ H_{3} + Cl - Cl ⟶ C H_{3} - Cl + Cl ∙$

Correct answer is (c) $C ∙ H_{3} + C ∙ H_{3} ⟶ C H_{3} - C H_{3}$

Q. Which of the following reaction has zero activation energy?

CH4​+Cl∙⟶C∙H3​+HCl

Cl2​⟶2Cl∙

C∙H3​+C∙H3​⟶CH3​−CH3​

C∙H3​+Cl−Cl⟶CH3​−Cl+Cl∙

Correct answer is (c) C∙H3​+C∙H3​⟶CH3​−CH3​

$C H_{4} + Cl ∙ ⟶ C ∙ H_{3} + H Cl$

$C l_{2} ⟶ 2 Cl ∙$

$C ∙ H_{3} + C ∙ H_{3} ⟶ C H_{3} - C H_{3}$

$C ∙ H_{3} + Cl - Cl ⟶ C H_{3} - Cl + Cl ∙$

Correct answer is (c) $C ∙ H_{3} + C ∙ H_{3} ⟶ C H_{3} - C H_{3}$
