Question

What is the total number of possible isomeric trimethylbenzene?

Answer 1

Hint: Isomers in chemistry are molecules or polyatomic ions that have the same molecular formula — that is, the same number of atoms of each element — but different atomic configurations in space. The existence or potential of isomers is referred to as isomerism. The chemical and physical properties of isomers are not necessarily the same.

Complete answer: The total number of possible isomeric trimethylbenzene is 3
The organic compound \[1,2,3 - trimethylbenzene\] has the chemical formula \[{C_6}{H_3}{\left( {C{H_3}} \right)_3}\] . It's an aromatic hydrocarbon, which means it's combustible and colourless. It's almost insoluble in water, but it's soluble in organic solvents. Coal tar and petroleum both contain it.
The organic compound \[1,2,4 - trimethylbenzene\] , often known as pseudocumene, has the chemical formula \[{C_6}{H_3}{\left( {C{H_3}} \right)_3}\] .
Mesitylene, also known as \[1,3,5 - trimethylbenzene\] , is a benzene derivative containing three methyl substituents symmetrically positioned around the ring. \[1,2,4 - trimethylbenzene\] and \[1,2,3 - trimethylbenzene\] are the other two isomeric trimethylbenzenes.

Note:
\[1,2,4 - trimethylbenzene\] is used as a solvent, as a paint and lacquer thinner, in the manufacture of colours, and in the production of prescription medications, in addition to being part of the chemical used as a gasoline additive. Breathing high quantities of \[1,2,4 - trimethylbenzene\] over short periods of time has an effect on the nervous system, resulting in headaches, fatigue, sleepiness, or dizziness. Coughing, wheezing, and/or shortness of breath are caused by inhaling \[1,2,4 - trimethylbenzene\] vapour, which irritates the nose, throat, and lungs. Muscle control issues, anxiety, and bewilderment are other indications of exposure. The effects \[1,2,4 - trimethylbenzene\] might appear immediately or shortly after exposure.
