The major product of this reaction exists as two stereoisomers. Draw both isomers. Show all hydrogen atoms in the structures. Use wedge and dash bonds to indicate the stereochemistry. An alkene where alkene carbon 1 has an ethyl and methyl substituent and alkene carbon 2 has a methyl and hydrogen substituent. The methyl substituents are on opposite sides of the alkene. This reacts with B r 2 and a large excess of water.
