Find the oxidation number of carbon in the following compounds: `CH_(3)OH, CH_(2)O, HCOOH, C_(2)H_(2)`.

Text Solution

Verified by Experts

Let the oxidation number of carbon be `a`.
`CH_(3)OH : a+3 xx 1+1xx(-2)+1xx1 = 0 rArr a = -2`
`CH_(2)O : a+2xx1+1xx(-2) = 0 rArr a = 0`
`HCOOH : 1+a+2xx (-2)+1 = 0 rArr a = +2`
`C_(2)H_(2) : 2xxa+2xx1 = 0 rArr a = -1`
