How many different alkenes result when 2-bromohexane is treated with a strong base?Select answer from the options below1  2  3  4

The answer is 3.

Here's the step-by-step explanation:

1. The reaction of 2-bromohexane with a strong base will result in an elimination reaction, specifically E2 elimination, which forms alkenes.

2. The bromine atom on the 2-bromohexane can be removed, and a hydrogen atom from either the 1st or 3rd carbon can also be removed, resulting in the formation of an alkene.

3. If the hydrogen atom is removed from the 1st carbon, the resulting alkene is 1-hexene.

4. If the hydrogen atom is removed from the 3rd carbon, the resulting alkene is 2-hexene.

5. However, 2-hexene has two different geometric isomers: cis-2-hexene and trans-2-hexene.

6. Therefore, the reaction of 2-bromohexane with a strong base can result in three different alkenes: 1-hexene, cis-2-hexene, and trans-2-hexene.
