Possible Exp. 7

Question 1

An alcohol can be converted to an alkene through ___________

Answer 1

Acid catalyze dehydration

Question 2

Explain the process of dehydration

Answer 2

A molecule of water from adjacent carbon atoms is eliminated

Question 3

How is dehydration most often brought about? (What methods?)

Answer 3

Heating the alcohol with either phosphoric acid or sulfuric acid

Question 4

The most difficult alcohols to dehydrate are _________

Answer 4

Primary alcohols

Question 5

Why are primary alcohols harder to dehydrate?

Answer 5

They require stronger acids such as concentrated sulfuric acid coupled with strong heat (around 180)

Question 6

Secondary alcohols, such as the one in this lab, undergo dehydration (more, less) easily than primary alcohols

Answer 6

More

Question 7

Secondary alcohols require (higher, lower) temperatures to perform the acid catalyze dehydration and form an __________

Answer 7

Lower, alkene

Question 8

What are the easiest of the three types of alcohols to dehydrate?

Answer 8

Tertiary alcohols

Question 9

When do beta elimination reactions occur?

Answer 9

When molecules such as HCl, HBr, HI, or in the case of this lab H2O, are eliminated from two adjacent carbons

Question 10

What are the two types of bet elimination reactions?

Answer 10

E1 and E2
