- What products (including stereoisomers, if applicable) are formed from the reaction of 3-bromo-3-methylpentane: a. with HO-? b. with H2O?https://www.bartleby.com/solution-answer/chapter-83-problem-6p-organic-chemistry-9th-edition/9781305080485/when-an-unsymmetrical-alkene-such-as-propene-is-treated-with-n-bromosuc-cinimide-in-aqueous/b3feeb25-a92a-11e9-8385-02ee952b546e#B: Methyl acetate has methoxy, -OCH3 as the remaining of the alcohol part in the ester. Isopropyl acetate has isopropoxy, -OCH(CH3)2 as the remaining of the alcohol part in the ester. -OCH(CH3)2 is more electron donating than the methoxy, -OCH3 group due to the presence of two electron-donating -CH3 group in the former. Hence saponification reaction of Isopropyl acetate is much slower than methyl acetate. Hence the rate of saponification of methyl acetate, CH3CCO2CH3 is 50 times greater than that for isopropyl acetate.
- Give IUPAC name of the following molecule and indicate Z or E. Answer all four of themProvide the E2 mechanism for β-elimination reactionemploying 2-chloro-2-methylbutane to prepare 2-methyl-2-butene and 2-methyl-1-butene reaction. Use the actual structures of thereactants and products. Explain which of the alkenes is the major product ofthis reaction ?Which of the following statement/s is/are false about the reaction of 3-methylhex-3-ene with H3O+?
- 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 reactionsDraw the products formed when both cis- and trans-but-2-ene are treated with OsO4, followed by hydrolysis with NaHSO3 + H2O. Explain how these reactions illustrate that syn dihydroxylation is stereospecific.On the line drawn below, provide the systematic (IUPAC) name for the following structure. Besure to include stereochemistry (R/S, cis-trans, or E/Z) when appropriate
- Like alcohols, ethers undergo a cleavage by breaking a carbon–carbon bond between an alkyl group and the carbon bonded to the ether oxygen atom; that is, the red C–C bond in R–CH2OR' is broken.

A 0.5 gram sample of hoodia gordonii isolated from natural sources yields an observed rotation of -0.76° when dissolved in 20 mL of chloroform and placed in a 1-dm cell. Determine the specific rotation [α] of hoodia gordonii for: (a) the entities as defined above,(b) an increase in solute from 0.5g to 1.0 g;(c) an increase in solvent from 20 mL to 40 mL; and (d) an increase in path length from 1 dm to 2 dm.Write IUPAC names for the compounds below.
