What are the condensed formulas of the five isomers of C6H14?
We know that the compound is an acyclic alkane, since it has chemical formula of the
There are only a finite number of such alkanes.
To avoid missing out on any, it pays to do things systematically. I usually go in decreasing length of longest carbon chain.
So first it is longest carbon chain = 6, which corresponds to n-hexane. Then I go for longest carbon chain = 5, which are the 2-methylpentane and 3-methylpentane. And so on.
The names of the above list:
