چکیده
|
The gutman index, schultz index, multiplicative degree-kirchhoff index, additive degree-kirchhoff index are four well-studied topological indices, which are useful tools in qspr and qsar investigations. spiro compounds are an important class of cycloalkanes in organic chemistry. in this paper, we determine the expected values of these indices in the random spiro chains, and the extremal values among all spiro chains with ݊ hexagons.
