Write an equation showing the formation of each of the following from the appropriate bromide:

(a) Isopropenyllithium

(b) sec-Butyllithium

Sample Solution (a) In the preparation of organolithium compounds from organic halides, lithium becomes bonded to the carbon that bore the halogen. Therefore, isopropenyllithium must arise from isopropenyl bromide.
