Which of the following statements are incorrect?

(A) In the presence light, $C{l}_2$ dissociates to give 2Cl radicals which react with ${\text{CH}}_{\text{4}}$ via free

radical mechanism.   

(B) Br radical being less reactive is less influenced by the probability factor. The bromination

primarily depends on the reactivity of H atom which is 3° > 2° > 1°

(C) If methane is not in excess,${\text{CH}}_{\text{2}}{\text{Cl}}_{\text{2}}$ , starts forming if the concentration of ${\text{CH}}_{3}Cl$ becomes more than that of ${\text{CH}}_{\text{4}}$. This is contain used and thus ${\text{CHCl}}_3$ and $CC{l}_4$ may also be formed.

(D The reaction between ${\text{CH}}_{\text{4}}{\text{\hspace{0.17em}and\hspace{0.17em}F}}_{\text{2}}$ is very vigorous. It can take place even in the dark or at room temperature.
