Statement 1 : Oxidation number of Carbon in CH2O is zero.Statement 2 : CH2O formaldehyde, is a covalent compound.

Both statements are true .Oxidation number can be calculated using some rules. H is assigned +1 oxidation state and O has oxidation number -2∴   O. No. of C in CH2O:       O. no. of C + 2(+1) + (-2) = 0 ∴   O. No. of C=0
