In CH3F H is +1 (this is not a bond to a reactive metal), F is -1 (F is alway -1 in its compounds), and C is then has the balancing -2, as overall the sum of the atomic oxidation numbers in a molecule is zero.
CH2Cl2 Four sigma bonds as the central carbon is bonded covalently to two hydrogens and two chlorine's.
oxidation number of I is -1. oxidation number of F is +1.
Zn has oxidation number +2; S has oxidation number -2
The oxidation number for H is +1, and the oxidation number for O is -1.
