Answer
The formula C6H14 shows that there should be no degree of unsaturation in the isomers, meaning there should be no rings, double bonds, or triple bonds. This is because the number of hydrogens is 2 more than twice the number of carbons (2x6+2=14).
Work Step by Step
Possible isomers can have a parent chain of 6,5,or 4 carbons, with some substituent alkyl groups (in this case methyl groups). See image.
