1. (25 pts) Write structural formulas for the products that form when 2-pentene reacts with each of the following reagents: a. HII b. $${\mathrm{H}}_2,\mathrm{Pt}$$ c. $${\mathrm{Br}}_2$$ in $${\mathrm{CCl}}_4$$ d. $$\mathrm{Hg}(\mathrm{OAc})2$$ in $$\mathrm{THF}$$ and $${\mathrm{H}}_2\mathrm{O}$$, then $${\mathrm{NaBH}}_4,{\mathrm{HO}}^{?}$$ e. $${\mathrm{BH}}_3:\mathrm{THF}$$, then $${\mathrm{H}}_2{\mathrm{O}}_2$$, $${\mathrm{HO}}^{?}$$ 2. (30 pts) By using the same alkene, how do you synthesize the following alcohols? Give the alkene and show the mechanisms for each product formation. 3. (15 pts) Give the structure of the products that you would expect from the reaction of 1butyne with: a. One molar equivalent of $$\mathrm{Br}2$$ b. One molar equivalent of $$\mathrm{HBr}$$ c. Two molar equivalents of HBr 4. (30 pts) Propose a synthesis route for the following conversion (it may include more than one step). $$?$$
