Question

Only one of the following reactions actually gives the provide product, the other reactions actually give different products. Identify the correct reaction, (ignore stereochemistry in this problem) A 4-ethyl-3-heptene BH_3.THF NaOH/H_2O_2 B 2-ethyl-2-heptene H_2O/Hg(OAc)_2/NaBH_4 3-ethyl-3-heptene BH_3.THF NaOH/H_2O_2 D 3-ethyl-3-heptene H_2O/Hg(OAc)_2 NaBH_4 Give the best reagents/conditions to perform the following reaction A H_2O/H_2SO_4 (cat.) B BH_3.THF NaOH/H_2O_2 C conc. H_2SO_4/heat D Hg(OAc)_2/H_2O NaBH_4

Explanation / Answer

4) c

Hydroboration oxidation follow antimarkonikov regioselectivity.

5) d

Oxymercuration demercuration follow markonikov regioselectivity without rearrangement.
