Question

(45 pts.) Provide anylall missing products or reactants foe the following reaction equaons All required reagents or catalysts mustbe included for ful credit. Clearly indicate proper stereochemistry and/oe regiochemistry where appropriate. If more than one isomer is possible all must be shown for full eredit. Mechanisms are not necessary, but my belp as a method of "sbowing work" for partial credit. b. H2S04 +H20 ? +Br Most stable configuration

Answer 1

Reaction (a) is simple Markovnikov's addition reaction of HCl in which more substituted product is preferred.

Reaction (b) is addition of water on alkene which is acid catalyzed and it is regioselective reaction in which nucleophile addition occurs on a specific site only, so it also follows markovnikov's rule for addition.

Reaction (c) is anti addition of Br₂ on alkene.

Reaction (d) is described in the mechnism.
