Chemistry · Isomerism: structural and stereoisomerism
How many structural isomers of that have a six membered ring and trisubstituted?
How many structural isomers of \( \boldsymbol{C}_{\mathbf{9}} \boldsymbol{H}_{\mathbf{1} \mathbf{8}} \) that have a six membered ring and trisubstituted?
- A. 3
- B. 4
- C. 5 \)
- D. 6
Step-by-step solution
The only way to have a six-membered ring and three substituents with C9H18 is to have three methyl groups on a cyclohexane ring (trimethylcyclohexane). The distinct constitutional isomers (ignoring stereochemistry) are 1,2,3; 1,2,4; 1,3,5; 1,1,2; 1,1,3; and 1,1,4-trimethylcyclohexane, totaling 6.
