The video tutorial explains the process of drawing the Lewis structure for HFOO. It begins by identifying the total number of valence electrons and arranging the atoms with hydrogen on the outside. The tutorial then details the placement of electrons to form chemical bonds, ensuring that the octets for oxygen and fluorine are satisfied. The video concludes by discussing the importance of formal charges and why the chosen structure is optimal, considering electronegativity differences.
