Organic Chem multiple choice

Which of the following is true about halogenation of an alkene? The reaction is regiooselective with Markovnikov product(s). The reaction is stereoselective with syn addition. The reaction is stereoselective with anti addition. The reaction proceeds through the most stable carbocation intermediate. A halohydrin forms when the ion reacts with as a nucleophile. See Figure 7-2. Which of the alkenes drawn would give only one product upon acid catalyze hydration? A B C D E F See Figure 7-2. Even though oxymercuration followed by reaction with NaBH_4 does NOT result in carbocation formation or carbocation rearrangement, Compound A in Figure 7-2 would form two different products. Those two products are I II III IV See Figure 7-2. Acid catalyzed hydration of Compound A would form which product(s)? (Choose all that apply.) I II III IV
