Organic chemistry student Everett has set up two separate electrophilic addition reactions with 2-butyne (shown below). In reaction (i) the alkyne is treated with 1 equivalent of HBr, which successful provides (Z)-2-bromo-2-butene. In reaction (ii) the alkyne is subjected to a two-step hydroboroation/oxidation sequence. Interestingly, Everett’s second reaction fails to provide the desired methyl ketone and instead has provided butan-2,3-diol. (a) Provide the structure of intermediate X form the first step of reaction (ii). (b) Briefly explain (use structures if necessary) why reaction (i) provided an alkene where as reaction (ii) provided an alkane when only 1 equivalent of the electrophile was used in each reaction.
Draw a complete stepwise mechanism for the Friedel-Crafts alkylation reaction shown below. You must show the structures of all intermediates and indicate electron flow with curly arrows. Draw only one of the resonance forms for the carbocation intermediate.
Draw Out Your Predictions of This Reaction: Part A: S-2-chlorohexane + NaOCH3NaOCH3 in methanol. (There are three elimination products and one substitution product.) Part B: 2-chloro-2-methylbutane heated in ethanol
Enolates are formed by deprotonation of an α-carbon hydrogen. Answer the following questions about enolate formation. In the molecule shown, select the α-carbon hydrogen that would be removed to form an enolate when NaOEt is used as a base. Draw the thermodynamic enolate that results for the molecule in Part 1. Draw only the enolate resonance form that includes a formal charge on the α carbon. Be sure to indicate that formal charge as well as any lone pair of electrons in your answer.
Any help with these would be great! Thanks in advance:) What is the major product of the reactions?

The two Grignard reactions and the reduction reaction below are all believed to have similar mechanisms. Use the curved arrow formalism to draw a single mechanism for these reactions using :Nuc-1 to indicate the nucleophile. The reacations are: cyclohexylmagnesium chloride + acetone in ether --> 2-cyclohexyl-2-propanol phenylmagnesium bromide + acetone in ether --> 2-phenyl-2-propanol Acetone + NaBH4 --> 2-propanol
I need help on the order of the listed reagents to make the final product.
A ketone undergoes acid-catalyzed bromination, acid-catalyzed chlorination, racemization, (see page 408)and acid-catalyzed deuterium exchange at the a-carbon. All of these reactions have similar rate constants.What does this tell you about the mechanisms of these reactions?
Enolates are formed by deprotonation of an α-carbon hydrogen. Answer the following questions about enolate formation. In the molecule shown, select the α-carbon hydrogen that would be removed to form an enolate when sodium hydroxide is used as a base. (use photo to answer this question). Then, Draw the thermodynamic enolate that results for the molecule in Part 1. Draw only the enolate resonance form that includes a formal charge on the α carbon. Be sure to indicate that formal charge as well as any lone pair of electrons in your answer.
