OH 3. What are the expected major products of these eliminations? Could you use the same technique as you used in your experiment to isolate these products? Explain your answers. Amberlyst-15 OH Amberlyst-15

Please, I need help with the question below. I will rate it  Explain which mechanism is predominant in each of the above elimination reactionsand how it affects the product formation.  Thank you for your help.

Use the reaction given below to answer the following questions. A CH₂OH B H₂O+ C + CH3NH3* D a) What are the approximate pKas of compounds A and B? b) The reaction given above is irreversible. Give a detailed explanation of the reaction and reaction mechanism. Your explanation should indicate your knowledge of the reactivity of carboxylic acid derivatives.

b).. .. Under each potential product of this E2 elimination, write "major product," "minor product," or "not formed." Me Br H Me Me OH Me Ph Ph H Me H Et Me Me Me Ph Ph Me Me Et

Multi-step synthesis. Give the reagents over the arrows and the intermediates between thearrows that are required to synthesize the product compound on the left from the reactant givenon the right for each retrosynthetic analysis.

Consider the following reaction. What is the role of LDA? CH2CH3 CHCO Et 1. LDA, THF 2. CH3CH₂Br CHCO₂Et LDA acts as a nucleophile and is substituted by the THF. LDA acts as a base and removes a proton from the alpha carbon to form the enolate. LDA acts as an electrophile and adds to the alkyl halide so it is easier to substitute. LDA acts as an acid to protonate the carbonyl carbon to form a good electrophile.

3. Propose a plausible mechanism for the following transformation. HO ОН H2SO4
