Chemical properties of methane

1. The bum in oxygen to form water and carbon (iv) oxide

CH_4(g) + 2O_2(g)  →   CO_2(g) + 2H₂O_(L)

2. They are undergo substitution reaction with chlorine in presence of ultraviolet light

CH_4(g) + CL_2(g) →  CH₂CL_2(g) + HCL_(g)

CH₂CL_2(g) + CL_2(g) →  CH2CL_2(g) + HCL_(g)

CH₂CL_2(g) + CL_2(g) →  CHCL_3(L) + HCL_(g)

CHCL_3(L) + CL_2(g) →  CCL_4(L) + HCL_(g)
