Determine whether methylcyclohexane contains a chiral center. How many different substituents do you count at atom

methylcyclohexane does not possess a chiral center

Explanation:

A molecule is said to possess a chiral center if one or more of the atoms in the molecule is bonded to four different atoms or groups.

If we look at methylcyclohexane, none of the carbon atoms in the molecule is bonded to four different atoms or groups hence the molecule contains no chiral centers and will not exhibit optical isomerism.

So, methylcyclohexane has a plane of symmetry thus it is an achiral molecule.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
