|---|---|---|---|---|---|
| Part A Vocabulary Review 1. hydrocarbons with only single bonds | saturated hydrocarbons
🗑
|
||||
| 2. hydrocarbons that have at least one double or triple bond | unsaturated hydrocarbons
🗑
|
||||
| 3. most compounds that contain carbon | organic compounds
🗑
|
||||
| 4. large molecules made up of many smaller organic molecules that have formed new bonds and are linked together | polymers
🗑
|
||||
| 5. organic compounds whose structural formulas contain the benzene ring | aromatic compounds
🗑
|
||||
| 6. biological compounds that contain twice as many hydrogen atoms as oxygen atoms | carbohydrates
🗑
|
||||
| 7. polymers formed from amino acids | proteins
🗑
|
||||
| 8. compounds with the same chemical formula but different molecular structures and shapes | isomers
🗑
|
||||
| 9. polymers that control the activities and reproduction of cells | nucleic acids
🗑
|
||||
| 10. small molecules that form links in polymer chains | monomers

| 13. made up of only carbon and hydrogen atoms | hydrocarbon
🗑
|
||||
| 14. process of separating petroleum into its individual compounds by boiling point | fractional distillation
🗑
|
||||
| 15. biological compounds that include fats and oils | lipids
🗑

🗑
|
||||
| Part B Concept Review 1. C6H6 is the formula for benzene. Benzene’s carbon atoms have three single bonds and three double bonds. In the space provided, draw the structural formula for benzene. | Hint: Benzene is a ring structure; when drawing this make sure you have 8 electrons around every oxygen; use your notes since I can't draw this on study stacks.
🗑
|
||||
| 2. Phenol is an aromatic compound made up of a benzene molecule with an –OH group substituted for one of the hydrogens. Its formula is C6H5OH. In the space below, draw the structural formula for phenol. | You can redraw the Benzene ring and substitute a -H with an -OH which makes it a substituted hydrocarbon
🗑
|
||||
| 3. How are monomers and polymers related? | monomers are the individual molecules that make up polymers
🗑
|
||||
| Classification and Example 4. used in structure and repair of body tissues | d and l
🗑
|

🗑
|
||||
| 6. substituted hydrocarbon with –OH groups replacing hydrogen | b and k
🗑
|
||||
| 7. Its structural formula contains the benzene ring. | a and j
🗑
|
||||
| 8. combines through peptide bonds | g and i
🗑
|
||||
| 9. contains same elements as carbohydrates but in different proportions | e and n
🗑
