How many isomeric alkenes are possible by the dehydration of 2,3-dimethyl butan-1-ol?

Explanation

To determine how many isomeric alkenes can be formed by the dehydration of 2,3-dimethylbutan-1-ol, we will follow these steps:

### Step 1: Draw the Structure of 2,3-Dimethylbutan-1-ol
The molecular structure of 2,3-dimethylbutan-1-ol can be represented as follows:
- The main chain is butane (4 carbon atoms).
- There are two methyl groups attached to the second and third carbon atoms.
- The hydroxyl (–OH) group is attached to the first carbon.
