**Question:**Which of the following accurately shows the curved arrows for an E2 reaction?**Diagram Descriptions:****(A)**- The diagram shows a tertiary amine on the left side with a lone pair of electrons.- A curved arrow originates from the lone pair of the nitrogen and points towards a hydrogen atom on an adjacent cyclohexane ring.- A second curved arrow points from the H atom’s bond to the bond between the carbon and iodine on the cyclohexane ring.- The iodine is depicted leaving the molecule.**(B)**- Similar setup with a tertiary amine and cyclohexane.- A single curved arrow originates from the lone pair on nitrogen directly to the iodine, bypassing the hydrogen.**(C)**- A tertiary amine is present with a lone pair of electrons.- A curved arrow goes from the nitrogen's lone pair to the hydrogen atom on the cyclohexane ring.- Another arrow goes from the H-C bond to the C-I bond, resulting in the iodine leaving.**(D)**- Again, there is a tertiary amine.- A curved arrow comes from the lone pair on nitrogen to the hydrogen on cyclohexane.- Another arrow goes directly from the C-I bond with no intermediate step via the H-C bond.**Explanation:**- Options (A) and (C) depict a two-step arrow process, involving both the H-C bond and C-I bond, typical for the abstraction step in an E2 reaction.- Option (B) incorrectly suggests the lone pair attacks iodine directly.- Option (D) misrepresents the positions and roles of bonds involved in a proper E2 elimination reaction.

The bicyclo [3.1.0] hexane ring system, highlighted in compound 3, is found in several natural products, including sabinene, a compound partially responsible for the flavor of ground black pepper. One method for preparing this ring system involves the conversion of compound 1 to compound 2, as shown below. Draw the structure of compound 2 and provide a reasonable mechanism for its formation. Add any remaining curved arrows to complete step one of the mechanism, and modify the given drawing as needed to show the intermediate that is formed in this step.
Please show the mechanism with arrow formalism.
