You prepare 4-ethyl-5,6-dimethyl-2-heptanol from an unsaturated hydrocarbon using suitable reagents so that only the desired product is formed.

a) Present a reaction equation that shows the structural formulas of organic compounds and the necessary reagents.

b) Present the detailed reaction mechanism, i.e. the arc arrows describing the movement of electrons, and the structures of the compounds occurring in the reaction.

c) Justify the choice of starting material and reagent. Tell what kind of intermediate step the reaction goes through to become a product, and why it happens.

d) Point out the electrophiles and nucleophiles in the different stages of the reaction.

I figured I should use 4-ethyl-5,6-dimethyl-1-heptene and acid catalyzed hydration, but don't know how to explain my conclusions. Please help.
