I need help with to solve this! 1. List the following carbonyl compounds in order of decreasing reactivity toward nucleophilic attack. CH CH3CH2CHCCCH2CH3 CH3CH2 CHCCH2CH3 CH3CH 2CH CH, CH CH CH3CH2CCH2CH3 CH3CH2CHCCHCH2CH3 CH CHCH CCH CH CH3 CH CH3 2. Each of the 30 alcohols below can be synthesized three different ways starting with a carbonyl compound and a Grignard reagent. Provide those syntheses for each alcohol shown. OH OH CH.
Please answer all! VA. Propose a pair of starting materials required for the synthesis of the products shown below. Each pair should consist of an appropriate carbonyl compound and Grignard reagent. LOH Carbonyl compound Grignard reagent Carbonyl compound Grignard reagent Carbonyl compound Grignard reagent VB. Propose a short, forward synthesis for the formation of the given product starting with benzyl alcohol. In the box provided, show the structure of an intermediate that would form in your synthesis. You may use...
I need help on all of these! Please help with d-h, if possible! d. The reaction of (2R)-butanol with NaBr and sulfuric acid in acetone proceeds with inversion of configuration. e. The addition reaction of HBr to 1-butene in the presence of peroxides produces the anti- Markovnikov product. (Might not be a review question, might make an appearance in early 3060.) The reaction of 2-methyl-2-butanol with HCl produces as a major product an alkyl halide. An ether and an alkene...
The four constitutionally isomeric alcohols shown below can each be made selectively by one or both of hydroboration/oxidation or oxymercuration/demercuration of one or two constitutionally isomeric alkenes. For each of (a)-(d) write one or two alkenes (as indicated) that is/are appropriate starting materials, and for each alkene which of two reagent combinations is needed to produce the indicated alcohol. You can disregard stereochemistry in this problem, and focus just on regiochemistry. In other words, be sure the OH will become...
help please! Propose the best synthetic route to do the following transformation Draw dearly the different intermediates indicating their stereochemistry if present. (More than one step it needed). Propose a complete and detailed mechanism for the products to the following reaction Propose a synthetic route to produce the following alkyl halides from the starting material given. And draw the complete mechanism for the synthesis. Devise a stepwise mechanism for the following reaction Draw the products of the following reaction, indicating...
