Explanation:
When 2-chloro-2-cyclobutyl hexane reacts with alcoholic KOH and heat, it undergoes an elimination reaction to form alkene products. The reaction mechanism is as follows:
Step 1: Deprotonation
Alcoholic KOH acts as a base and deprotonates the hydrogen from the β-carbon of the chlorocyclobutane to form a cyclobutene carbanion.
Step 2: Elimination
The carbanion is unstable and undergoes elimination of the leaving group (chlorine) to form a double bond in the cyclobutene ring. This process is known as E2 elimination.
Step 3: Rearrangement
The cyclobutene ring is strained and can undergo a ring expansion to form a cyclopentene ring.
Overall reaction:
2-chloro-2-cyclobutyl hexane → cyclobutene → cyclopentene
Total number of alkene products:
From the above mechanism, we can see that there are four possible alkene products that can be formed:
1. 1-methylcyclopentene
2. 3-methylcyclopentene
3. 1,2-dimethylcyclopentene
4. 1,3-dimethylcyclopentene
Therefore, the total number of alkene products is 4.
