Simmons–Smith reaction of cyclohexene with diiodomethane gives asingle cyclopropane product, but the analogous reaction of cyclohexene with 1,1-diiodoethane gives (in low yield) a mixture of two isomeric methylcyclopropane products. What are the two products, and how do they differ?
Iodine azide,, adds to alkenes by an electrophilic mechanism similar to that of bromine. If a monosubstituted alkene such as 1-butene is used, only one product results:

c)
In light of the result observed when,adds to 1-butene, what is
the polarity of thebond? Propose a mechanism for the reaction
using curved arrows to show the electron flow in each step.
The reaction of cyclohexene with mercury(II) acetate in CH3OH rather than
H2O, followed by treatment with NaBH4, yields cyclohexyl methyl ether rather than cyclohexanol. Suggest a mechanism.

Question: In planning the synthesis of one compound from another, it’s just as important to know what not to do as to know what to do. The following reactions all have serious drawbacks to them. Explain the potential problems of each.
