OChem HELP... Draw the conformational structures (chair or boat conformations) for the MAJOR product formed when 1-tert-butylcyclohexene reacts with each of the following reagents. Also, indicate if the product obtained is racemic form. a) Br2, CCl4 b) Br2, H2O c) OsO4, then aqueous NaHSO3 d) ICl e) mCPBA, then H3O+, H20 f) O3, then Me2S (conformational structure not required) g) BH3:THF, then H2O2, HO- h) D2, Pt i) Hg(OAc)2 in THF-H2O, then NaBH4, HO- j) BD3 :THF, then CH3CO2T
Based on the more stable conformation (conformation A), need help providing two mechanisms for the E2 elimination of the protonated version of cis-1 using a general base (B:) to give alkenes 2 and 3. Clearly show which hydrogens meet the stereochemical requirements for E2-elimination Using Zaitsev’s rule, indicate which is favoured. Pictured is also a reaction mechanism to show what the alkenes 2 and 3 are. Thank you :)

What starting alkene reacted with I2 in a solution of CH2Cl2 is required to produce 1,2-diiodoocyclopentane?
I have a trans-3-chloro-1-methylcyclopentane. I react it with ethanol with heat. Knowing heat favors elimination, I suspect 3-methyl-cyclopentene as a product. Will I also get the substitution product 3-methoxy-1-methylcyclopentane, a pair of enantiomers and a pair of diastereomers?
A chemist allows some pure (2S,3R)-3-bromo-2,3-diphenylpentane to react with a solution of sodium ethoxide(NaOCH2CH3) in ethanol. The products are two alkenes: A (cis-trans mixture) and B, a single pure isomer. Under thesame conditions, the reaction of (2S,3S)-3-bromo-2,3-diphenylpentane gives two alkenes, A (cis-trans mixture) and C.Upon catalytic hydrogenation, all three of these alkenes (A, B, and C) give 2,3-diphenylpentane. Determine the structuresof A, B, and C; give equations for their formation; and explain the stereospecificity of these reactions

Addition of HBr to allene (CH2 = C = CH2) forms 2-bromoprop-1-ene rather than 3-bromoprop-1-ene, even though 3-bromoprop-1-ene is formed from an allylic carbocation. Considering the arrangement of orbitals in the allene reactant, explain this result.
