Verified step by step guidance1
Identify the central atom in the molecule. In SBr2, sulfur (S) is the central atom.
Determine the number of valence electrons for the central atom. Sulfur has 6 valence electrons.
Count the number of bonding pairs and lone pairs around the central atom. SBr2 has two bonding pairs (from the two Br atoms) and two lone pairs on the sulfur atom.
Use the VSEPR (Valence Shell Electron Pair Repulsion) theory to predict the molecular geometry. According to VSEPR theory, the presence of two bonding pairs and two lone pairs results in a bent molecular geometry.
Visualize the molecular shape: The lone pairs repel the bonding pairs, causing the molecule to adopt a bent shape similar to that of water (H2O), where the angle between the bonds is less than 180 degrees.
