Chapter 4 Worksheet

1. Using your answer from #2, complete the following chart on carbon (5pts).

Carbon

Atomic Number

Atomic Mass

Number of valence electrons

Maximum number of bonds it can form with other atoms

Type of bond carbon forms with other molecules

2. Using the model below to complete the electron configuration of a carbon atom or state how many electrons are in each energy shell. (2pts)

Energy shell 1:___________ electrons

Energy shell 2:___________ electrons

3. Why is carbon’s electron configuration essential to life? (2pts)

4. An alien might classify the human organism as a “carbon-based lifeform.” Does this mean that we are organic or inorganic? Explain your answer. (2pts)

6. Who was Stanley Miller? How did his work contribute to the field of organic chemistry? (2pts)

7. Describe how the shapes of carbon-based compounds contribute to molecular diversity. (2pts)

8. Some scientists think that life elsewhere in the universe might be based on the element silicon, rather than on carbon, as on Earth. Look at the electron distribution diagram for silicon on Fig. 2.7 and draw the electron configuration for silicon. What properties does silicon share with carbon that would make silicon-based life more likely than, say, neon-based life or aluminum-based life? Explain your answer. (2pts)

9. Study the image of this complex molecule below. Which part(s) of this chemical can be considered a hydrocarbon? Circle this region(s), and then explain why. (2pts)

10. Classify the pairs of molecules below as structural isomers, enantiomers, or cis-trans isomers . If it is a cis-trans pair of isomers, label the cis isomer and the trans isomer correctly under the picture. (6pts)

A. ______________________

B. ______________________

C. ______________________

D. ______________________

E. ______________________

F. ______________________

11. In the following images, Identify at least two functional groups attached to each substance (by circling them), and name these chemical groups. You cannot name the same chemical group more than once. (6pts)

Note- If you have a hard time circling the chemical group, write the name under the structure: hydroxyl, carbonyl, carboxyl, amino, sulfhydryl, phosphate, methyl

12. Summarize what you learned in this chapter (in your own words). (2pts)
