Draw a curved arrow mechanism that accounts for the cyclisation of 2 into F [ please make sure your mechanism takes into account stereochemical considerations including the stereoselectivity of the reaction and clearly indicate if a conrotatory or a disrotatory process is responsible for each of the transformations]. can you please explain how you decide and select the stereoselectivty and how to see if its conrotatory or disrotatory so that i can apply to similar questions. thank you
For the dehydrohalogenation (E2) reaction, draw the Zaitsev product, showing the stereochemistry clearly. You might find it helpful to make a model of the starting material to determine the correct conformation.
Working Backwards Parte Deux. a.First, identify which functional groups changed during the reaction. Did stereochemistry change too? b. Based on your answers to A and B, what kind of reaction occurred here, SN1 or SN2? c.Suggest reagents and solvent that could accomplish this reaction.
a. What are the products of following reactions?b. Write the reaction mechanism for each using the right arrows and define it as Sn2, Sn1, E2 or E1.c. Explain why do you choose that product and mechanism or in case something else happens explain why.
When 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?
2. In not more than three (3) sentences, explain why terminal alkynes are acidic.3. What impurities are removed when acetylene gas is made to pass through an acidifiedsolution of CuSO4?4. Explain the difference in the rate of free radical bromination reactions of toluene and cyclohexane.
For 1 and 2, identify the predominant type of reaction: SN1, SN2, E1 and E2. Draw the major products only. Show stereochemistry whenever applicable.
