Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub
Total number of cyclic structure isomers possible with
Answer:
Solution:
The question asks for the total number of cyclic structural isomers possible with the molecular formula .
Solution:
The general formula indicates that the compound could be an alkene or a cycloalkane. Since we are looking for cyclic structures, we are dealing with cycloalkanes.
1. Cyclopentane: A five-membered ring.
2. Methylcyclobutane: A four-membered ring with a methyl substituent.
3. Ethylcyclopropane: A three-membered ring with an ethyl substituent.
4. 1,1-Dimethylcyclopropane: A three-membered ring with two methyl substituents on the same carbon.
5. 1,2-Dimethylcyclopropane: A three-membered ring with two methyl substituents on adjacent carbons. Note that this has cis and trans isomers, but the question asks for structural isomers, not stereoisomers.
Therefore, there are 5 cyclic structural isomers of .
