2. When a compound with multiple alkenes reacts with ooe equivalent of a reagent, typically the 5. Alkynes andergo many of tha same renctions as alkenes. The major exceptions are hydration most reactive alkene will preferentially react. Provide the major product from each of the (which provides carthonyl products), and hydrogenation (that can be storpeed at an alkene fallowing reactions. depending on resction embitions). I'rovibe the major products from each of the following reactions of alkynes. (s) inj 3. For bydrogenation, you cannot add only one cquivalent. With PdC, all alkenes (and alkynes) present will be hydrogented (other metal catnlysts can give berter control, but we will not cover them in 124). A similar situntion oxcurs with acid-catalyzed hydrntion reactions where it is id) ditticult ta add omly one uivalent. Provide the major product from each of the folkowing reactions. (a) 4. When conducting anti-Markovnikoy hydration, BH ? will preferentially react at the less substituted alkene (or alkyne) due to sterics (this is the only exception when the le5s reactive (g) (f) alkene may react furst if it is less hindered). Provide the major product from each of the following reactions. 6. One way to prepare a coujugated alkewe is from an alkene via allylic bromination with NBS, hv followed by E2 elimination with a stong base ( NaOH,NaOO an, etc). Provide the major products from the following reaction sequeace. 2. When a compound with multiple alkenes reacts with ooe equivalent of a reagent, typically the 5.
