Question
Consider the mechanism for the following reaction: The "one product'' would be The "one product" would be the substitution product with "S" stereochemistry. The initial event in the mechanism would be attack at the alpha-carbon by the acetate ion. The mechanism for this reaction would incorporate bond-making and bond-breaking in one step with no distinct intermediates. A positively charged carbon ion is called a CARBANION. Identify the choice that best completes the statement or answers the question. Choose the statement(s) that is/are NOT TRUE. A. Zaitsev's Rule will result in the least substituted alkene product(s). B. Rule only is valid for E2 type reaction mechanisms. C. Zaitsev's Rule predicts the elimination reaction will occur with the inversion of configuration. D. Zaitsev's Rule results in the beta-Hydrogen attached to the LEAST substituted carbon atom being removed to give the most stable product. E. ALL statements are NOT TRUE.Explanation / Answer
A. NOT TRUE. Zaitsev's rule results in the most substituted alkene products. This is the primary definition fo this rule for elimination reaction.
B. NOT TRUE. The rule is applicable to both E1 and E2 reaction mechanism.
C. NOT TRUE. The rule doesn't make any generalizations for the stereochemistry of alkene formed, but only the regioselectivity of the product formed.
D. NOT TRUE. It directs the abstraction of hydrogen with most substituted carbon. So that alkene formed is most substituted.
E. TRUE. All statements are NOT TRUE. :D
