Topic 48: Nomenclature of Alkenes

48.1How do we calculate the degree of unsaturation of compound based on its molecular formula? In particular, how is that done when there are atoms such as O, N, S, and Cl present?
 
48.2Why is it useful to be able to calculate the degree of unsaturation? (That is, when can we use it?)
 
48.3How are the rules for naming alkenes similar to the rules for naming alcohols?
 
48.4How do we name compounds that are both alkenes and halides? Alkenes and alcohols?
 
48.5When is it appropriate to refer to the alkene stereochemistry as cis or trans? When must we instead use E and Z ?
 
48.6What do E and Z refer to? Why are they named that?
 
48.7What do methylene, vinyl, and allyl refer to?
 
48.8In propene, is the electron density shifted more toward the C=C or toward the CH3? Why? What effect does this have on the chemistry of alkenes?
 

Topic 49: Alkenes - Synthesis

49.1What are four ways you can think of for how to make alkenes? (one from halides and three from alcohols) What are the pros and cons of each of these methods?

364 Questions for Organic I

Dearest Student. This web page is a set of questions I call Detailed Intended Learning Outcomes For Organic Chemistry (Part I). Some time ago I asked myself, "Bob, what do you think are the key questions that you hope students will be able to answer after taking Chemistry 247 at St. Olaf College?" So here you have them. Some are very simple; some require more thought. All are good questions to be thinking about as you read, discuss, and master the practical aspects of organic chemistry. They are discussion starters and review tips. There are no answers here (though there are some clues). The questions are here to help you focus on what's important (to me, at least!) and organize your learning process. The questions are grouped into topics. Bite-size chunks. Take them a few at a time. Don't feast on them all at one sitting!
