Summary: Given \(H\), a hexagonal chain, we determine an expression of its second-order general connectivity index, denoted by \({}^2\chi_\alpha(H)\), in terms of inlet features of \(H\). Moreover, by applying the method in integer programming theory, we completely determine the extremal chains with the minimal or maximal \({}^2\chi_\alpha(H)\) over the set of hexagonal chains.
