What is the change in oxidation number of carbon in the following reaction? CH 4 g + 4 Cl 2 g → CCl 4 + 4 HCl g
Options
- A0 to + 4
- B– 4 to + 4
- C0 to – 4
- D+ 4 to + 4
Correct answer
B. – 4 to + 4
Step-by-step solution
CH 4 g + 4 Cl 2 g → CCl 4 l + 4 HCl g Oxidation number of carbon in CH 4 x + 4 × + 1 = 0 x = - 4 Oxidation number of carbon in CCl 4 x + 4 × - 1 = 0 x = + 4 Change in oxidation number is - 4 to + 4
