The F-index or “Forgotten topological index” of a molecular graph is defined as the sum of cubes of degrees of all the vertices of the graph. In this paper, we compute the F-index of bridge and chain graphs. Further using these derived results, the F-index of several classes of chemical graphs and nanostructures are computed.
