- Arrange the structure on the image with regard to the reactivity towards hydrolysis. 1 being the least and 3 being the mostWhen drawing organic chemistry mechanisms with NaOCH3, do we automatically dissociate it into Na+ and OCH3-, making it easier to go through SN2 and/or E2 reactions? Does NaOCH3 dissociate, and is this why it is a strong nucleophile?A student was given from the list of the compounds below A, B and D blindly and asked to identify them all. He treated each of them with Brady's reagent (2,4-ditrophenylhydrazine) and isolated a bright yellow compound for one of them, but the other two gave false negatives. The student reasoned that the false negatives may be due to sterics and, on further thinking, it dawned on him that he might be able to rule out one of the false negatives with the haloform test. What compound did he find compatible with the haloform test? That compound did indeed give a false negative in the Brady test. Which of the other two was positive in the Brady test? A = haloform B = Brady A = haloform D = Brady B = haloform A = Brady B = haloform D = Brady D = haloform A = Brady D = haloform B = Brady

You should include all products. Include counter-ions, e.g., Na+, I-, in your submission, but draw them in their own separate sketcher. Separate structures with + signs from the drop-down menu.Suggest reactivity of compound A, B and C in increasing order of E2 reaction

Provide the stereochemistry of the product.
- Compelling evidence for the existence of a tetrahedral intermediate in nucleophilic acyl substitution was obtained in a series of elegant experiments carried out by Myron Bender in 1951. The key experiment was the reaction of aqueous −OH with ethyl benzoate (C6H5COOCH2CH3) labeled at the carbonyl oxygen with 18O. Bender did not allow the hydrolysis to go to completion, and then examined the presence of a label in the recovered starting material. He found that some of the recovered ethyl benzoate no longer contained a label at the carbonyl oxygen. With reference to the accepted mechanism of nucleophilic acyl substitution, explain how this provides evidence for a tetrahedral intermediate.Compelling evidence for the existence of a tetrahedral intermediate in nucleophilic acyl substitution was obtained in a series of elegant experiments carried out by Myron Bender in 1951.
