The video tutorial explains how to draw two water molecules forming hydrogen bonds. It covers the molecular geometry of water, highlighting the bent shape due to lone pairs and the unequal sharing of electrons between hydrogen and oxygen, which makes water a polar molecule. The tutorial demonstrates how hydrogen bonds form between a lone pair on one water molecule and a hydrogen atom on another, allowing for up to four hydrogen bonds per molecule. The video concludes with tips on drawing these bonds and emphasizes the polar nature of water.
