The general $ Z $-type index is a molecular descriptor, introduced recently by Chen and Lin [Discrete Optim., 50 (2023), 100808], which generalizes several well-known molecular descriptors, including the (general) sum-connectivity index and (general) Platt index. The primary objective of the current paper is to study the largest value of the general $ Z $-type index of graphs in the class of all fixed-order trees (and chemical trees) with a particular number of segments.
