- A problem often encountered in the oxidation of primary alcohols to acids is that esters are sometimes produced as by-products. For example, oxidation of ethanol yields acetic acid and ethyl acetate: Propose a mechanism to account for the formation of ethyl acetate. Take into account the reversible reaction between aldehydes and alcohols:arrow_forwardWhen cyclohexene is reacted with hydrobromic acid in acetic acid, the major product is bromocyclohexane. There is a small amount of cyclohexyl acetate formed. What is the mechanism that forms both compounds? What is the purification procedure that isolates both compounds?arrow_forwardDescribe a sequence of reactions by which cis-2-pentene could be prepared from acetylene.arrow_forward
- Draw the formulas of the reactants and products of the reaction: 2-ethylbutanoyl bromide with excess ethylmagnesium bromide and heating the product with concentrated H2SO4.arrow_forwardWhen 2-iodo-1,4-dimethylcyclohexane is heated in acetic acid, CH3COOH, a mixture of substitution and elimination products is obtained. Provide structures for all possible products, writing [not drawing] the name of the mechanism by which each one is formed.arrow_forwardDraw all of the substitution and elimination products formed from the given alkyl halide with each reagent: (a) CH3OH; (b) KOH. Indicate the stereochemistry around the stereogenic centers present in the products, as well as the mechanism by which each product is formed.arrow_forward
- When propene reacts with gaseous hydrogen bromide, HBr, two products, 1-bromopropane and 2-bromopropane are formed. The reaction is a two-step process in which the electrophilic attack occurs in the first step. Identify the electrophile in this reaction Draw a diagram showing the first step of the reaction that leads to the production of 2-bromopropane.arrow_forwardPredict the b-elimination product(s) formed when each bromoalkane is treated with sodium ethoxide in ethanol. If two or more products might be formed, predict which is the major productarrow_forward1) Nucleophilic substitution reaction of alkyl halide is a process when nucleophile replace the leaving group of alkyl halide. Propose the mechanism and product(s) for the following substitution reaction.arrow_forward
- Two substitution products result from the reaction between 3-chloro-3-methyl-1- butene with sodium acetate (CH3COO – Na +) in acetic acid under SN1. Identify the products.arrow_forwardAn alkene is treated with OsO4 followed by H2O2. When the resulting diol is treated with HIO4, the only product obtained is an unsubstituted cyclic ketone with molecular formula C6H10O. What is the structure of the alkene?arrow_forwardThe SN2 reaction is an example of a nucleophilic substitution reaction. Draw the structure of the two reactants and the mechanism of the reaction. The reaction is 1-bromo-3-ethylpentane reacts with cyclohexanol under basic conditions.arrow_forward
