First Order Elimination generally follows the following form:
The first step requires the loss of the leaving group, forming a
carbocation intermediate. A base then attacks a neighboring hydrogen
forming the double bond.
Rate Equation: Rate
Points to Watch:
polarity is unimportant. Works best in a good ionizing solvent
substituted substrates work best 3 deg > 2 deg. Primary and
methyl halides don't react.
strength is unimportant because the base is not
involved in the rate-determining step
goes by carbocation intermediate, rearangements can occur.
||Good leaving group
required (ie. halide, tosylate, etc)
