I need help designing an experiment using a secondary halide, 2-bromohexane or 2-bromoheptane as the beginning material. I know that the things I need to do are use NaOH, -OH, and CH3OH to come up with the products of an alkene and secondary alcohol. I need specific reactions, materials, and procedures. I then plan to use GC/
Predict the structure of the diphenylquinone product, C28H40O2 by the oxidative coupling of 2,6-di-tert-butylphenol with oxygen in the presence of base. (Show work)
In contrast to SN2 reactions, SN1 reactions show little nucleophile selectivity; that is, when more than one nucleophile is present in the reaction medium, SN1 reactions show only a slight tendency to discriminate between weak and strong nucleophiles, whereas SN2 reactions show a marked tendency to discriminate. a. Provide an
When the alkyl bromides (shown below) were subjected to hydrolysis in a mixture of ethanol and water (80% CH3CH2OH/20% H2O) at 55OC, the rates of the reaction showed the following order: (CH3)3CBr > CH3Br > CH3CH2Br > (CH3)2CHBr Provide an explanation for this order of reactivity.
1-Bromobicyclo[2.2.1]heptane is extremely unreactive in either SN1 or SN2 reactions. Provide explanations for this behavior.
Although ethyl bromide and isobutyl bromide are both primary halides, ethyl bromide undergoes SN2 reaction more than 10 times faster than isobutyl bromide. When each compound is treated with a strong base/nucleophile (CH3CH2O-), isobutyl bromide gives a greater yield of elimination product than substituted products, whereas eth
Isoprene (2-methyl-1,3-butadiene) reacts with the following: (1) hydrogen chloride (1 mole equivalent) in ether (2) deuterium chloride (1 mole equivalent) in ether (3) bromine (1 mole equivalent) in carbon tetrachloride (4) excess hydrogen gas in the presence of a PtO2 catalyst (5) excess mercury (II) acetate and methanol f

Three compounds A, B and C all have the formula C5H10. A and B rapidly decolourise bromine dissolved in CH2CL2 but compound C is unreactive. Compound A reacts rapidly with acidified water and a tertiary alcohol D is formed; however compound B yields a secondary alcohol. (a) Draw a possible structure for each of A, B and C.
