Draw the mechanism and predict the products (including all possible stereoisomers) for the reaction of the reactant below (whose name is: H3CH2C н Hас Нас CH3 (a) with hydrogen bromide. Also consider: after forming the product(s) what reagent(s) and conditions need to be used in order to reform the above reactant? (b) with hydrogen bromide with alkyl peroxide. would hydrogen chloride or hydrogen bromide work in this reaction? (c) with dilute aqueous solution of sulfuric acid. Also consider: after forming the product(s) what reagent(s) and conditions need to be used in order to reform the above reactant? (d) with i) mercuric acetate and water followed by ii) sodium borohydride (no mechanism is needed for this second step). Also consider: what is the name of this reaction? What product would form if ethanol was used in place of water? what would be the name of that reaction? (e) with i) borane in tetrahydrofuran followed by ii) hydrogen peroxide in sodium hydroxide (no mechanism is needed for this second step); what is the name of this reaction? (f) with bromine with bromine and water (h) with NBS in the presence of light (i) with bromoform with aqueous sodium hydroxide; what would the products be if the following reagents were used: i) methylene iodide with copper-zinc alloy (what is the name of this 888
