In the theoretical chemistry, pharmacology and biology literature, numerous VDB topological indices were introduced to predict physio-chemical properties of chemical compounds. As a kind of polycyclic aromatic hydrocarbons, f–benzenoids are abundant in real substances such as coal tar, etc. It is valuable to study the attributes of f–benzenoids by virtue of topological indices. The main dedication of this paper is to obtain extremal values for VDB topological indices of f–benzenoids with a given order. Furthermore, the extremal f–benzenoids attaining these values are also characterized.
