CHEM 210 Chapter 10 Test Questions and Answers All Correct

CHEM 210 Chapter 10 Test Questions and Answers All Correct Organic Chemistry - Answer-the study of the compounds of carbon Organic Compounds are - Answer-- made up of carbon and other elements: hydrogen, oxygen, and nitrogen Also present in some organic compounds are: - Answer-- sulfur, phosphorus, and a halogen (F, Cl, Br, I) CO2 is inorganic because: - Answer-it is less reactive and contains no hydrogen Why are we carbon based life-forms, instead of Si or Ge based life forms? - Answer-- They are all tetrahedral, but Carbon is on the edge. Carbon is +/-, can make at least 3 bonds. - Carbon tetrahedral bonds allow for both straight chain and branch chain polymers. tetrahedral shape gives the least steric hindrance in 3 dimensions. - Answer-Less than 4 bonds = you cant achieve all the possible shapes. What is totally organic? - Answer-- sugar, Meat - Starch, vegetables - Fruit, Milk - Gasoline, plastics, insecticides/ herbicides, drugs (steroids, hormones) Why is organic chemistry a separate discipline within chemistry? Hist. - AnswerHistorical: Scientist at one time believed that a "vital force" present in living organisms was necessary to produce an organic compound, Why is organic chemistry a separate discipline within chemistry? Discov. - Answer-The experiment of Wohler in 1828 was the first in a series of experiments that led to the demise of the vital force theory. The sheer number of organic compounds - Answer-- Over 10 million and growing - By comparison, 1.7 million inorganic - 85% of all known compounds are organic - With an estimated 10,000 new ones discovered/made each year Link to bio chemistry - Answer-Carbohydrates, lipids, proteins, enzymes, nucleic acids, hormones, vitamins, and almost all other chemicals in living systems are organic compounds
