QUESTIONS AND ANSWERS .

• What is a major difference between organic and inorganic compounds? -

Correct answer-organic contain carbon

• What is the reason why there are so many organic compounds? -

Correct answer-carbon atoms can form stable covalent bonds with other carbon atoms

• The vast number of organic compounds is due to the unique chemistry

of carbon. This chemistry involves - Correct answer-formation of long chains& isomerism

• Which applies to the manner in which carbon bonds in alkanes? -

Correct answer-the bonds are formed with carbon using an sp3 configuration

• Functional groups are - Correct answer-to organic chem as polyatomic

ions are to inorganic chem, are chemically bound to each other in order to develop larger molecules

• The alkanes represent one family of organic compounds - Correct

answer-that is composed of carbon and hydrogen

• Formulas of organic compounds - Correct answer-CH3CH2COOH,

CH3CH2OH,

8. CH3CH3CH3

• Which is an alcohol - Correct answer-CH3CH2OH

• What is meant by the term "saturated" when describing hydrocarbons
• Correct answer-they are saturated with hydrogen and only have single

bonds between carbons

• Correct statements on the naming of organic compounds - Correct

answer-many compounds have been known long enough to have common names, the naming system of organic compounds is set by IUPAC rules, & the naming system requires that the longest carbon chain must always be found

12. Cycloalkanes are - Correct answer-NOT: compounds that have a flat

molecular structure,
