Total number of constitutional isomers possible for trimethyl cyclohexane is .......
Show Hint
When determining the number of isomers, consider all possible ways the substituents can be arranged on the ring, taking into account symmetry and uniqueness of the resulting structures.
Step 1: Structure of trimethyl cyclohexane.
Trimethyl cyclohexane consists of a cyclohexane ring with three methyl groups attached at various positions.
Step 2: Analyzing the isomers.
- The methyl groups can be attached to different positions on the cyclohexane ring, leading to multiple constitutional isomers. By considering different possible locations for the methyl groups, there are 6 possible isomers.
Step 3: Conclusion.
The total number of constitutional isomers is \( \boxed{6} \).
