Question

Determine whether each of these reactions occurs through an SN1, SN2, E1, or E2 mechanism. A. A cyclohexane ring with a bromide on carbon 1, a methyl on carbon 2, and an isopropyl on carbon 4 is treated with ethanethiol in ethanol. The product is a cyclohexane ring with a methyl and SCH2CH3 group on carbon 1 and an isopropyl group on carbon 3. Identify the mechanism of reaction A. E1 SN1 SN2 E2 B. A cyclohexane ring with a bromine on carbon 1 and an isopropyl group on carbon 4 is treated with ethanol to give a cyclohexane ring with an ethoxy substituent on carbon 1 and an isopropyl group on carbon 4. Identify the mechanism of Reaction B. E2 E1 SN2 SN1 C. A cyclohexane ring with a bromide on carbon 1 and an isopropyl group on carbon 4 is treated with the sodium salt of ethanethiol in acetone. The product is a cyclohexane ring with an SCH2CH3 on carbon 1 and an isopropyl group on carbon 4. Identify the mechanism of Reaction C. E2 SN1 SN2 E1
