The video tutorial explains the Lewis structure of sulfuric acid (H2SO4). It begins by introducing the structure, highlighting the placement of sulfur in the center due to its lower electronegativity, surrounded by four oxygens and two hydrogens. The tutorial details the distribution of 32 valence electrons to form bonds and fill octets. It emphasizes the importance of checking formal charges, noting that sulfur can hold more than eight electrons. By forming double bonds with oxygens, the formal charges are adjusted to zero, resulting in a more stable structure. The video concludes with a reminder to always verify formal charges.
