Unit 7 Waycross College CHEM 2401K

GENERAL OBJECTIVES

The learner will demonstrate a knowledge of the alkenes including structures, and preparations.

SPECIFIC LEARNING OBJECTIVES

The learner will:

1. draw a structure of ethylene, explain sp² hybridization, locate σ and Π bonds in ethylene.

2. name and draw structures of different alkenes.

3. draw cis- and trans- isomers of different alkenes (and indicate which one is E or Z).

4. understand, explain and draw the mechanisms involved in the dehydrohalogenation of alkyl halides.

5. list the ease of dehydrohalogenation of primary, secondary, and tertiary alcohols and to recognize the proper products of this type of reaction.

6. understand, explain, and draw the mechanisms involved in dehydration of alcohols.

7. write equations for and understand mechanisms involved in the dehalogenation of vicinal dihalides.

8. be familiar with the physical properties of alkenes.

9. be familiar with the stability of alkenes and cycloalkenes

10. be familiar with the use of alkenes in industry.
