CHEM 30. QUESTIONS AND ANSWERS FORFREQUENTLY ASKED QUESTIONS. UPDATED FOR
2024/2025 EXAM PREP
1 . Inorganic carbon containing compounds:
1 . carbon oxides- C02 2. cyanides- CN
3. carbides- SiC
4. carbonates- C03
2. Organic compounds contain which type of bonds: Covalent
bonds
3. Carbon is unique because: 1. it can bond with other carbons to
form sheets, spheres, tubes, rings, chain, etc
2. it can form combinations of single, double and triple bonds
4. Polar bonds are formed when: There is an uneven pull on
electrons
5. Polar compounds are formed when: The polar bonds within a
molecules do not cancel eachother out
6. What are isomers: Compounds with the same chemical formula but
different structures
7. Different isomeric structures result in different: Properties
8. Why do isomers have different propteies: The different arrangement
of atoms deteremines the intermolecular forces within compounds,
which in turn determine the boiling point and solubility of
compounds in water
9. What are petrochemicals?: Chemicals created from fossil
fuels
10. Examples of petrochemicals: 1 . methanol- (windshield
antifreeze)
2. ethylene glycol- ( radiator antifreeze)

19. Formula for alkanes: CnH2n+2
20. What are Alkanes: Hydrocarbons containing only single bonds
21. Properties of Alkanes: 1. non-polar - therefore insoluable in water
