- For each reaction, give the expected solution product and predict whether the machanism will be first order (SN1) or second order (SN2) : a) 2-chloro-2-methylbutane +CH3COOH b) isobutyl bromide + NaOMe c) 1-iodo-1-methylcyclohexane + CH3CH2OH- For the dehydration shown, use curved arrows to show the formation of the carbocation intermediate in the presence of sulfuric acid H2SO4H2SO4, then draw the structures of the minor and major products of the elimination. Picture: Cyclohexane (no double or triple bonds) with a methyl group and an alcohol group (HO 4e- on O) on C1 (bottom) reacting with H2SO4 -> "Major and Minor Products" -The H2SO4H2SO4 is abbreviated as H+H+ in the drawing module. Do not delete any pre‑drawn bonds, charges, or lone pairs. If you accidentally make a mistake, remove the last change by using the undo button on the lower left or revert the drawing palette to the original state by selecting the More menu, then select Reset Drawing. Step 1: Use curved arrows to complete the protonation mechanism of the alcohol. Step 2: Use a curved arrow to show the formation of the carbocation intermediate for the elimination.

- Assume that 2-chloropropane reacts with CN− in an SN2 reaction. Use the JSME editor () to draw the structure of the substitution product of the reaction. The guide on how to draw your structure can be found here Important Note: When drawing the structures in the JME editor please adhere to the following formats: 1. If the nucleophile is OH−, DO NOT manually add the "H" to the final product 2. If the nucleophile is CN−, be sure to include the appropriate bonding between the C and N in the final productThe experiment shown shows that the proximity of the chloride ion to C-2 in the transition state causes the 1,2- addition product to form more rapidly than the 1,4-addition product. a. Why was it important for the investigators to know that the preceding reaction was being carried out under kinetic control? b. How could the investigators know that the reaction was being carried out under kinetic control?Assign the stereochemical configuration (E or Z) for the alkene below. Show your work, indicating clearly which groups are assigned high priority (e.g., through assigning the groups numbers, circling only the high priority groups, or labeling groups as high or low).
