- CCH H20, H2SO4 H9SO4 CH3 Alkynes do not react directly with aqueous acid as do alkenes, but will do so in the presence of mercury(II) sulfate as a Lewis acid catalyst. The reaction occurs with Markovnikov regiochemistry, so the OH group adds to the more highly substituted carbon and the H adds to the less highly substituted carbon. The initial product of the reaction is a vinyl alcohol, also called an enol. The enol immediately rearranges to a more stable ketone via tautomerization. Draw curved arrows to show the movement of electrons in this step of the mechanism.

- Which represents an efficient synthetic route to go from an alkane to an alkene? O elimination with NaNH2, followed by a water workup O anti-Markovnikov hydrohalogenation, followed by elimination O radical bromination, followed by elimination O hydration, followed by elimination O hydration, followed by ozonolysis of the double bondarrow_forwardCan you please draw the structure of the major product that results in each steparrow_forwardIntermidiates and reagents of the following two final products from a Acetylene Note: the final products are different reactions but use the same starting material.arrow_forward
- Provide the product(s) for the reaction of benzene with Br2, FeBr3. If more than one product is formed, list the major product first. If no reaction, draw the starting material.arrow_forwardMarkonikov's rule states that with the addition of a protic acid HX to an asymmetric alkene, the H or electropositive part gets attached to the carbon with more alkyl substituents, and the X group or electronegative part gets attached to the carbon with more hydrogens.

- Q2arrow_forwardDraw the structure of the expected organic product(s) formed in the following reactions including correct stereochemistry. If the product is racemic write both isomers or write racemic. Assume all reagents listed are present in excess unless otherwise noted. If no reaction occurs, state 'No Reaction'arrow_forwardTwo substitution products result from the reaction between 3-chloro-3-methyl-1- butene with sodium acetate (CH3COO – Na +) in acetic acid under SN1.
