Answer:
Five.
Explanation:
There are five isomers that is present in hexane (C⁶H¹⁴) which consist of n- hexane, 2- methyl pentane, 3- methyl pentane, 2, 3-dimethylbutane and 2, 2- dimethylbutane. 2- methyl pentane is also known as Isohexane while on the other hand, 2, 2- dimethyl butane also known as Neohexane. These isomers have the same molecular formula which is C6H14, and having the same molecular weight which is 86.
