In each case below select the synthetic procedure/s that could be used to carry out the transformation, giving the alcohol shown as the single major product. The procedures are: Hydroboration/oxidation: alkene + BH3; then H2O2, OH. Oxymercuration: alkene + Hg(OAc)2, H₂O; then NaBH4 H CH3CH2- C CH3 CH2CH3 х CH3 CH3 OH OH CH3CH2CHCHCH3 CH2CH3 HO CH3 CH3

Provide the major product(s) of each reaction below. Show the stereochemistry of each stereocenter (for example, by using wedge-dash structures for chirality centers and clear bond angles for alkenes). For enantiomers, you only need to draw one of the enantiomers. Br2, H₂O 1) 03 2) MeSMe H₂, Pd/C HgSO4 H₂SO4 H₂O 1) BH3 2) NaOH, H₂O2 H₂O 1) 9-BBN 2) NaOH, H₂O2 H₂O

Please help me answer these organic chemistry questions. Explanations are welcome/

Provide the organic product(s) formed in the highest yield for each reaction below. If more than one product is provided, label the product formed in the highest yield "MAJOR" if it is possible to determine. Include counterions to balance charges in your answer and indicate stereocenters whenever appropriate. HO D OH xes N cho ia NaOH/H₂O, 100 °C 1. NaNH2 (2 equiv.)

2. Give the products when 1-methyl-2-deutero-cyclohexene is treated with the following reagents. Be sure to clearly show stereochemistry of product(s). 1) Hg(OAc)2, H,о 2) NABH, CCI, (an inert solvent) CH3 H2, Pd/C ELOH CH;OH H,SO,(cat.)

The following tertiary alkyl bromides undergo an SN1 reaction in aqueous acetone to form the corresponding tertiary alcohols. Rank the alkyl bromides from most reactive to least reactive.

Draw structural formulas for all alkenes that could be used to prepare the alcohol shown below by oxymercuration.
