Identlfying Chemieal Compounds

A. Study the rules and formulas below. Then, on the ilrst llne under each lormula, tell whether

the substa[ce is organic or inorganic. On the second line, indicate whether the substance is a

carbohydrate, fat or oil, protein or amino acid, or none ol ihese.

hulec !. All organic compoupds contain carbon. Moot lnorganic compounds

do not contain carbon. Carbon dioxide is an excepdon.

2. ln carbohydrate molecules, the rado of hydrogen to oxygen is 2:1.

3. In tate and oils, the ratio of hydrogen to oxygen is much greater than 2ll.

T4. Amino acids contain an amino group (-NHe or N*H-)

and an organic acid group (-{OOH or -f-OH)o
