Oxidation number of C in CH(3)OH,CH(2)O,...

Oxidation number of C in `CH_(3)OH,CH_(2)O,COOH and C_(2)H_(2)` is respectively :

A

`-2,0,+2,-1`

B

`+2,0,+2,-2`

C

`-2,0,+2,0`

D

`-2,-4,+2,-2`

Text Solution

Verified by Experts

The correct Answer is:
A
`CH_(3)OH: " " x+3-2+1 " " theredforex=-2`
`CH_(2)O: " " x+2-2 " " thereforex=0`
`HCOOH : " " 1+x-4+1 " " therefore x=+2`
`C_(2)H_(2): " " 2x+2 " " thereforex=-1`
