Question

the sum of the oxidation numbers of all the carbons in c6H5CHO is -

a) +2

B ) 0

c) +4

d) -4.

Answer 1

answer :-


C6H5CHO ,

let the O.S OF C present in C6H5CHO =x

so ,

7x + 6× 1 - 2 = 0

or 7x + 4 = 0 or x = -4 /7

since ,

the sum of o.n of all the carbon is C6H5CHO = -4 / 7 × 7 = -4
