Question
Following are two diastereomers of 3-bromo-3,4-dimethylhexane with sodium ethoxide in ethanol, each gives 3,4 dimethy1 J-hexeme as the major comer gives the E alkene, and the other gives the Z alkene. Which diastereomer gives the Z alkene?

1) Answer A
COmpound A has 3S, 4R configuration, hence on treating with base forms Z-alkene
2) Answer A
COmpound A has 3S, 4R configuration, hence on treating with base forms Z-alkene
3) Answer B
COmpound B has 3R, 4R configuration, hence on treating with base forms E-alkene
