Question

What are the isomers of ${\mathrm{C}}_6{\mathrm{H}}_{12}$?

Answer 1

Isomers:

• “Isomers are two or more compounds that have the same chemical formula but a different arrangement of atoms.”
• As the structures of isomers differ, thus the physical/chemical properties also differ.

The cyclic as well as non-cyclic compounds can be drawn using molecular formula ${\mathrm{C}}_6{\mathrm{H}}_{12}$. There are total $25$ possible isomers of ${\mathrm{C}}_6{\mathrm{H}}_{12}$ are:

• Cyclohexane
• 2,3−Dimethyl−1−butene
• 3,3−Dimethyl−1−butene
• 2,3−Dimethyl−2−butene
• 1,1−Dimethylcyclobutane
• 1,2−Dimethylcyclobutane
• 1,3−Dimethylcyclobutane
• 2−Ethyl−1−butene
• Ethylcyclobutane
• 1−Hexene
• 2−Hexene
• 3−Hexene
• 2−Methyl−1−pentene
• 2−Methyl−2−pentene
• 3−Methyl−1−pentene
• 3−Methyl−2−pentene
• 4−Methyl−1−pentene
• 4−Methyl−2−pentene
• 1,2,3−Trimethylcyclopropane
• 1,1,2−Trimethylcyclopropane
• Propylcyclopropane
• Methylcyclopentane
• Isopropylcyclopropane
• 1−Ethyl−1−methylcyclopropane
• 1−Ethyl−2−methylcyclopropane
