A straight-chain alkane differs from a cycloalkane in such a way that the straight-chain has more hydrogen than the cycloalkane. In this case, straight-chain has two more Hydrogen atoms than the cyclic alkane. Basically, they differ in the number of hydrogen atoms attached to the carbon. Straight-chain Alkane has a formula CnH2n+2 while cyclic alkane follows CnH2n.
