Question

B3: The following optically active oone optically active, one with no optical ac alkene, upon hydrogeraito explain this observation. n, yields two 4 pts H2 2 different products Pd/C CH3 B4: 1,3-butadiene, when treated with HBr, gives a mix of two product neither of which is 4-bromobut-1-ene. Predict both these products using mechanism that involves a single carbocation intermediate: 4 4-bromobut-1-ene Anot formed! HBr C5: Terminal alkynes are moderately acidic synthetically. When pent-1-yne is treated with a strong base [sodium am followed by 2S-bromobutane, a new alkyne re to predict the exact structure of both intermediate A and final p and this can be exploited de, sms sults.
