Question

Carbon is in highest oxidation state in:

• A. $C{H}_{3}Cl$
• B. $CC{l}_4$
• C. $CHC{l}_3$
• D. $C{H}_{2}C{l}_2$

Answer 1

The correct option is B $CC{l}_4$

Let oxidation state of carbon is $x$.

In $C{H}_{3}Cl$, $x+3(+1)+(-1)=0$

$x=-2$

In $C{Cl}_4$, $x+4(-1)=0$

$x=+4$

In $CH{Cl}_3$, $x+1+3(-1)=0$

$x=+2$

In $C{H}_2{Cl}_2$, $x+2(+1)+2(-1)=0$

$x=+0$

So $C{Cl}_4$ is correct answer.
