Question

If HOH in the presence of H_2SO_4 and Hg^+2 catalyst were mixed with 1 ethyl 2-isopropyl-1-cyclopentene, the MAJOR product would be____. Select one all four stereoisomers of 1-ethyl-2-isopropylcyclopentanol all four stereoisomers of 2 ethyl 1 isopropylcylopentanol the two stereoisomers of 2 ethyl-1 isopropylcyclopentanol with the two alkyl groups on opposite planes of the ring the two stereoisomers of 1-ethyl-2-isopropylcyclopentanol with the two alkyl groups on opposite planes of the ring the two stereoisomers of 1-ethyl-2-isopropylcyclopentanol with the two alkyl groups in the SAME plane of the ring the two stereoisomers of 2-ethyl-1- isopropylcyclopentanol with the two alkyl groups in the SAME plane of the ring none of these choices Both choice A and choice B

Explanation / Answer

If HOH is reacted with 1-ethyl-2-isopropylcyclopentene, under oxymercuration condition, the major product formed in the given reaction would be,

D. the two stereoisomers of 1-ethyl-2-isopropylcyclopentanol with the two alkyl groups on opposte planes of the ring.
