Predict the product(s) and provide a full arrow-pushing mechanism for the reaction of 4-methyl-1-hexyne with two equivalents of hydrobromic acid.

Part III, Reaction Mechanisms 16. (15 pts) Show the mechanism for the following transformation. осно aq NaOH H3O+ Мон + H3C-OH OH

Give detailed Solution with explanation needed..don't give Handwritten answer

Under acid-catalyzed conditions, epoxides can be opened by a variety of nucleophiles other than water, such as alcohols. In such a case, the nucleophile will generally attack at the more substituted position. Using this information, predict the products for each of the following reactions (a-b): ? 1) RCO-H 2) [H₂SOJ Modify the given structure to draw the major product(s). Use the single bond tool to interconvert between double and single bonds. If a racemic mixture of enantiomers is expected, draw both enantiomers. Note: you can select a structure and use Copy and Paste to save drawing time. CH₂ Edit Drawing A

Complete the reaction scheme below. Show all reagents and intermediates. No reaction is a possible answer. 1) CH3CH2M9B CH3OH H+ (ехcess) но 2) H30*, H2O B A OCH3

Please give the explanation of the concept and please provide detailed solution

A chemist needs an ether to use as a solvent for a reaction and wants to synthesize it in one step from two of the following available reagents: sodium ethoxide, bromomethane, potassium tert-butoxide, and 2-bromo-2-methylpropane. i) Which combination(s) will give a good yield of an ether? Illustrate, showing the mechanism of the reaction. ii) Illustrate with a mechanism the reaction of one of the combinations that will not yield an ether?

2) reaction sequences to carry out those transformations. Draw the expected product of each step proposed. Substantial partial credit can be obtained for incomplete or incorrect answers. You may present your solutions on the following blank page if you need the the following reaction transformations, and propose room. H3C CH, H3C CH3 of HN- -NH HO,C Co,H но H,C CH3 CEN OCH3 OCH3
