Solution

The image shows two structural formulas: CH3CH2CH2CH2OH and (CH3)2CHCH2OH. These are butan-1-ol and 2-methylpropan-1-ol. They have the same molecular formula, C4H10O, but differ in the arrangement of the carbon skeleton (chain). One is a straight chain, the other is branched. This difference in the carbon skeleton defines chain isomerism.

Final Answer: chain
