3-Chloro-1-butene reacts with sodium ethoxide in ethanol to produce 3-ethoxy-1- butene. The reaction is second order, first order in 3-chloro-1-butene, and first order in sodium ethoxide. In the absence of sodium ethoxide, 3-chloro-1-butene reacts with ethanol to produce both 3-ethoxy-1-butene and 1-ethoxy-2-butene. Explain these results.
When the alkyl bromides (listed here) were subjected to hydrolysis in a mixture of
ethanol and water (80% EtOH/20% H2O) at 55 °C, the rates of the reaction showed the
following order:
(CH3)3CBR > CH3Br > CH3CH2Br > (CH3)2CHBR
Provide an explanation for this order of reactivity.
9. (a) Under certain conditions, the reaction of 0.5 M 1-bromobutane with 1.0 M sodium
methoxide forms 1-methoxybutane at a rate of 0.05 mol/L per second. What would be the
rate if 0.1 M 1-bromobutane and 2.0 M NaOCH3 were used?
(b) Consider the reaction of 1-bromobutane with a large excess of ammonia (NH3). Draw
the reactants, the transition state, and the products. Note that the initial product is the salt
of an amine (RNH* Br) which is deprotonated by the excess ammonia to give the amine.
(c) Show another SN2 reaction using a different combination of an alkoxide and an alkyl
bromide that also produces 1-methoxybutane.

- Acetic anhydride reacts with water in the following manner: CH3C(O)-O-C(O)CH3 + H2O = 2CH3CO2 If this reaction is carried out in an inert solvent with low concentrations of both acetic anhydride and water, it follows the rate law rate = k [CH3C(O)-O-C(O)CH3] [H2O] with a rate constant of 0.0035 s-1.

The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH,Cl). In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed.

- OH NaOH H3C CH3 H3C CH3 Alkyl halides undergo nucleophilic substitution and elimination reactions. When the kinetics of the reaction are measured, if the rate of the reaction is found to be dependent only upon the concentration of the alkyl halide the reaction is first order. The substitution reaction is thus termed Sy1, and the elimination reaction is termed E1. These reactions are unimolecular and occur in two steps. The first step is rate-limiting and involves the loss of the leaving group to form a carbocation. In the second, fast, step the nucleophile adds to the carbocation in the SN1 reaction or elimination occurs to give an alkene in the E1 reaction. Because the carbocation is planar, the nucleophile can add to either face and therefore racemization is usually observed although solvent effects can influence this somewhat. E1 elimination follows Zaitsev's rule and typically yields the most substituted alkene as the major product. Conditions which favor the Sy1/E1 pathway include…arrow_forwardThe reaction of 2,2-dimethyl-1-propanol [(CH3)3CCH2OH], also known by the common name neopentyl alcohol, with HBr is very slow and gives 2-bromo-2-methylbutane as the major product.Give a mechanistic explanation for these observations.arrow_forwardPlease give the main substitution product for each of the following reactions, and indicate the dominant mechanism: (a) 1-bromopropane + NaOCH3 → (b) 3-bromo-3-methylpentane + NaOC2H5 →arrow_forward
