Oxidation Levels

Additional Exercises

1. Determine the oxidation level of each atom in the following compounds. Boldface type is used to specify a particular atom when necessary. Don't forget to include lone pairs of electrons. Check to make sure that the sum of the oxidation levels of all the atoms equals zero.

CH3CHF2	CH3	CHF2	H	F	--
					--
	CH2	CHCl	H	O	Cl
	CCH3	CH3	H	NH	NH2
	CH3	CH2	C	O	N
	HC	CH2	=O	-O-	Cl
	CF3	CH2	H	F	Br
	CH3	CH2	H	Mg	Br
	CH3	C	C-O	O-O	H
	Cl-C	C	H	O	Cl
	CH3	C	CH2	H	O

2. Sulfur and chromium are both Group 6 elements. Calculate the oxidation level of the sulfur and chromium atoms in the following compounds. Don't forget to include lone pairs of electrons where appropriate. Check to make sure that the sum of the oxidation levels of all the atoms equals zero.

H2S (hydrogen sulfide)	SO2 (sulfur dioxide)	SO3 (sulfur trioxide)	CH3SSCH3 (dimethyl sulfide)	(sulfuric acid)
(dimethyl sulfoxide)	CrCl3 (chromium trichloride)	CrO3 (chromium trioxide)	(chromic acid)	(sulfanilamide)
