please help with these E2 problems
Practice Identify the major and minor products for the E2 reaction that occurs when each of the following substrates is treated with a strong base. А. В.
3. Predict and label the major and minor products from the following E2 reaction. Justify your answer with figures which demonstrate the transition state leading to the products obtained (4 points) 4. When the two constitutional isomers, 3,3-dimethyl-1-butene and 2,3-dimethyl-2-butene, are reacted with HCl the same major product is formed. Explain the observation and identify the product.

Chem 2200 E1/E2 Practice Problems tn 1. Predict the major produc t in each of the following reactions Ha OEt b) Br Ph 2. 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....
6. Predict which of the following two isomers (cis- or trans-) will undergo an E2 elimination under the treatment with EtoNa in EtOH more rapidly. A) For the explanation of the reaction rate, draw chair conformations for each isomer, determine which conformation is more stable . B) Draw the major product and the mechanism of the reactions.
