Question

Give the mechanistic symbol (Sn1, Sn2, E1, E2) that are most consistent with each statement. There can be multiple answers per part:

A. Represents concerted processes:

B: Requires anti-periplanar geometry

C: Most likely to have been involved when products are found to have different carbon skeleton from substrate:

D. Alkyl iodides react faster than alkyl bromides in reactions that proceed these mechanisms:

E. In ethanol that contains sodium ethoxide, 3-bromo-3-methylpentane reacts mainly by this mechanism:

A. SN2 and E2 (both are one step process)

B. E2 (trans-anti geometry is required for E2 elimination to occur)

C. E1 and E2 (from saturated converted to unsaturated)

D. SN1, SN2 , E1 and E2

E. E1 (Substrate is sterically crowded and solvent is polar protic and also leaving group is -Br)
