Draw the reaction mechanism (reaction arrows) for any one of the reactions to show how the product is formed.arrow_forwardTo propose an intermediate and mechanism for the transformationsarrow_forward
- What is the mechanism of the reaction below.arrow_forwardDraw the mechanism for the conversion of propanedial (see Problem 7.43) in its keto form to its enol form under basic and acidic conditions. Do the same for the conversion from the enol form to the keto form.arrow_forwardCan you do 5,6,7 and explain it? State the mechanism in which through reaction proceeds sn2 or sn1 and can you explain the process of the mechanismarrow_forward
- Which step in the suggested mechanism is the rate-determining step (a) or (b)? Explain the answerarrow_forwardIn the reaction (E) 2-methyl -2,4-hexadiene with hydrogen bromide at room temperature, two isomeric products are isolated. Draw the structures for these isomeric products. Which is the kinetic isomer and which is the thermodynamic isomer.arrow_forwardFor the reduction of 2-methyl cyclohexanone to methyl cyclohexanol using NaBH4... 1. What is the reaction mechanism (draw curved arrows)? What is the nucleophile? Electrophile? 2. Using your reaction mechanism from the above question, sketch the reaction coordinatediagram. What does the transition state most likely look like? What is the rate-determining step?arrow_forward
