Consider the hydroboration of 1-pentene. Predict the major
outcome of this reaction through a transition state analysis and
construct a reaction coordinate diagram to justify your answer.
Note: the oxidation step after hydroboration does not have any
impact on regioselectivity.
1)
Consider these molecules:
1-pentene
2-pentene
2-methyl-2-butene
cyclopentane
1-methyl-cyclobutene
2-methyl-1-butene
Which is not a stereoisomer of the others?
2-pentene
cyclopentane
1-methylcyclobutene
2-methyl-2-butene
These are all stereoisomers of one another.
2)
Classify 3-methyl-2-butanol as a primary, secondary, or tertiary
alcohol.
Primary
Secondary
Tertiary
More information is needed to solve this.
It can be more than one of these.
3)
What must be present for an addition polymerization reaction to
occur?
Two hydroxyl groups (one on each molecule).
An acid.
An hydroxyl...
1)
Draw the mechanism and product of: basic hydrolysis of
propanenitrile.
2) Tylenol (acetaminophen) has a much longer shelf life than
aspirin. Explain.
1) Predict the sign, (+) or (-), for
∆H and ∆S for the following reactions.
