Question

in a reaction CH4 changes to CH2Cl2 then no gains of electron
​

Answer 1

Answer:

Let oxidation state of carbon is x.

In CH

4

, x+4(+1)=0

x=−4

In CH

3

Cl, x+3(+1)+(−1)=0

x=−2

In CCl

4

, x+4(−1)=0

x=+4

In CHCl

3

, x+1+3(−1)=0

x=+2

In CH

2

Cl

2

, x+2(+1)+2(−1)=0

x=+0

So option C) is correct answer.
