The general sum-connectivity index of a graph G is defined as , where d u denotes the degree of vertex u in G, E(G) denotes the edge set of G, and Ξ± is a real number. We determine the maximum value for the general sum-connectivity indices of n-vertex trees and the corresponding extremal trees for Ξ±
