1) Which carbocation is the most stable? a) CH2=CHCH2+ b) CH3CH=CH2+ c) CH3C=CH2(+ sign on top of H2) d) CH3CH2CH3
2) I have a 3-methyl-1-Pentyne compound starting in an only (s) configuration and I'm putting in H2 and Pt. The product of this reaction would be.... a) Only (S) b) Only (R) c) (R) + (S) d) Achiral
3) Same question as previous but instead of putting in H2 and Pt I'm putting in H2 and Lindlar's Catalyst.
Alkenes can be converted to alcohols by reaction with mercuric acetate to form a ?-hydroxyalkylmercury(II) acetate compound, a reaction called oxymercuration. Subsequent reduction with NaBH4 reduces
