Draw the structure of 

(a) A six-carbon alkene that would give the same product from reaction with HBr whether peroxides are present or not.

(b) Four compounds of formula C₁₀H₁₆ that would undergo catalytic hydrogenation to give decalin:

(c) Two alkenes that would yield 1-methylcyclohexanol when treated with Hg(OAc)₂ in water, then NaBH₄/NaOH:

(d) An alkene with one double bond that would give the following compound as the only product after ozonolysis followed by H₂O₂:

(e) Two stereoisomeric alkenes that would give 3-hexanol as the major product of hydroboration followed by treatment with alkaline H₂O₂:

(f) An alkene of five carbons that would give the same product as a result of either oxymercuration–reduction or hydroboration–oxidation.
