No

Explanation:

the reactivity of the halogens with CH_4 decreases with in the group due the less electronegativity

CH_4+4F_2=> CF_4+4HF at low temperature
CH_4+4Cl_2=>CCl_4+4HCl at slightly high temperature
CH_4+4Br_2=>CBr_4+4HBr(at moderatly high temperature)
CH_4+4I_2<=>_(catalyst)CI_4+4HI(even at high temperature)#
