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

The reaction of 2-bromohexane with a strong base will result in the formation of alkenes through an elimination reaction (E2 reaction). The base will abstract a proton from the carbon next to the one bearing the bromine, leading to the formation of a double bond and the expulsion of the bromide ion.

The possible alkenes that can be formed are:

1. 1-hexene: This is formed when the hydrogen atom is abstracted from the carbon atom next to the carbon bearing the bromine atom on the side closer to the end of the chain.

2. 2-hexene: This is formed when the hydrogen atom is abstracted from the carbon atom next to the carbon bearing the bromine atom on the side closer to the middle of the chain.

3. 3-hexene: This is formed when the hydrogen atom is abstracted from the carbon atom two positions away from the carbon bearing the bromine atom.

So, the answer is 3. Three different alkenes can be formed when 2-bromohexane is treated with a strong base.
