Here, it is crucial to understand that majority of the molecules will follow this rule but exceptions always exist in the chemistry. The molecular geometry of BeF2 is linear because according to VSEPR theory, valence shell electrons around the fluorine and beryllium atoms are going to repel each other since the central atom doesnt contain any lone pair, so, those two fluorine atoms are going to push far as much as they can to either side of beryllium central atom and that makes BeF2 is a linear molecule.
