The oxidation number of carbon is zero is

A

HCHO

B

`CH_2Cl_2`

C

`C_(6)H_(12)O_6`

D

`C_(12)H_(22)O_(11)`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
Consider the oxidation state of .c. as .x.
a) `HCHO =1 + x +1 -2 =0 impliesx =0`
b) `CH_(2)Cl_(2)=x+2(1)+2(-1)=0`
`x+2-2=0 implies x = 0`
c) `C_(6)H_(12)O_(6)=6 (x) + 12 (1) +6(-2)=0`
`6x +12 -12 = 0 implies 6x =0 :. x = 0 `
d) `C_(12)H_(22)O_(11)=12(x) +22(1)+11(-2)=0`
`12x +22-22=0 implies x =0`
