Alkyl Shifts: 1. Construct a reaction diagram including 2,3-dimethylbutan-2,3-diol and H2SO, as the reactants. Include all lone pairs of electrons. 2. Identify the nucleophile and the electrophile in the drawing above. 3. Draw a double headed arrow beginning at the nucleophilic lone pair of electrons on one of the oxygen atoms of 2,3-dimethylbutan-2,3-diol and ending on the electrophilic hydrogen of H2SO4. Make sure to push the electrons in the bond between the H and HSO. onto the HSO4 so that...
Draw the unique stereoisomers for 2-chloro-2,3-dimethylpentane.
Show stereochemistry clearly. To ensure proper grading, explicitly
draw all four groups, including wedge/dash bonds, around a
chirality center. Indicate whether the compounds could exist in an
optically active form.
suggest the perspective formula if all possible stereoisomers of 2,3-dinitrobutans. for those stereoisomers, predict the stereoisomer that is/are enantiomers, superimposible or non-superimposible mirror image; diastereoisomer and meso compound if it exist.
show all steps of these synthesis problems

Why does 2,3-dichlorobutane have only 3 stereoisomers?
Draw all stereoisomers associated with 2-Bromo-3-methypentane.
Draw the Fischer projections for all stereoisomers associated with
2-Bromo-3-methypentane. Clearly label all stereoisomers as either
enantiomers, diastereomers, or meso. Place the lowest priority
groups in two vertical positions in final display. SHOW ALL WORK
