The tosylate of (2R, 3R)-3-phenylbutan-2-ol undergoes an E2 elimination on treatment with sodium ethoxide. Draw the structure of the alkene that is produced. Use the wedge hash bond tools to indicate stereochemistry. You do not have to explicitly draw H atoms. If a group is achiral, do not me wedged or hashed bonds on it. Predict the major alkene product of the following E1 reaction: Amines are converted into alkene5, by a two-step process called the Hofmann elimination. S_N 2...
1. Following the guide on page 154, give the mechanism for the E2 reaction shown below. КОН CH3 H3CH2CH2C-C-C-CH2CH2CH3 H CH3 H2CH2CH2C-C-C-CH2CH2CH3 H BI 2. Each reaction shown below (a and b) produces three elimination products. Draw all possible products formed. Write "major" under the Zaitsev product. concentrated acid strong base

When 1-chloro-oox(Compound I) is treated with sodium methoxide in methanol, elimination readily occurs to give 1,2-x0oxd compound I). However, the two diastereomers of i (la and lb) each give one single isomer of il (either lla or lib) as shown below. Provide structures for la and ib as well as a mechanistic explanation for the stereopecificity....
For each of the following reactions, determine which ELIMINATION mechanism (E1 or E2) will occur. Alkyl Halide Substitution: Methyl 1° 2° 3° Base Strength: Strong Weak Mechanism Type: E1 E2 Draw the mechanism that leads to ALL products for the reaction. Finally, underline the major product of the elimination reaction: H3C OH H2C H2C1 Br CHE
For the following dehydrohalogenation (E2) reaction, draw the
Zaitsev product(s) resulting from the elimination involving C2-C3
(i.e., the carbon atoms depicted with stereobonds). Show the
product stereochemistry clearly. If there is more than one organic
prodcut, both products may be drawn in the same box. Ignore
elimination involoving C2 or C3 and any carbon atom other than C3
or C2.
For the following dehydrohalogenation (E2) reaction, draw the Zaitsev product(s) resulting from elimination involving C3-C4 (i.e., the carbon atoms depicted with stereobonds). Show the product stereachemistry clearly. If there is more than one organic product, both products may be drawn in the same box. Ignore elimination involving C3 or C4 and any carbon atom other than C4 or C3. KOH EtOH/heat
