Question

a) Evaluate the ability of the following molecules to undergo E2 elimination when heated with strong base.

b) Rank the compounds based on the rates at which they will undergo E2 elimination, 1 being the fastest and 4 being the slowest. Explain why, 

The image depicts four chemical structures labeled as a), b), c), and d). Each structure is a cyclohexane ring with substituents attached, indicating stereochemistry through the use of solid (wedge) and dashed (hatched) lines. All structures include the tosylate group (OTs) as a substituent.

a) The cyclohexane ring has a tosylate group (OTs) attached with a solid wedge line, indicating that it is facing above the plane of the ring. There are two other substituents: one isopropyl group is attached with a solid line and another smaller group is attached with a dashed line, indicating its orientation below the plane.

b) This structure also has a tosylate group (OTs) positioned above the plane (dashed line). An isopropyl group is attached with a solid wedge above the plane, and another substituent is depicted with a solid line in the plane of the ring.

c) In this structure, the tosylate group (OTs) is shown above the plane (solid wedge), but without clarity on the exact position due to the ring configuration. An isopropyl group projects out of the plane with a solid wedge, and another substituent is oriented below the plane with a dashed line.

d) The cyclohexane ring features a tosylate group (OTs) above the plane of the ring (solid wedge), similar to structure a. This structure shows an isopropyl group in the same orientation (solid line) and a smaller group below the plane (dashed line).

These structures represent different stereochemical configurations of a tosylate substituted cyclohexane, important in understanding the physical and chemical properties of such compounds.
