T-shaped molecular geometry

T-shaped molecular geometry is a type of molecular arrangement that occurs in certain molecules with a central atom bonded to three other atoms and with one lone pair of electrons. This geometry is typically associated with the VSEPR (Valence Shell Electron Pair Repulsion) theory, which predicts the shape of molecules based on the repulsions between electron pairs around a central atom. In T-shaped molecules, the central atom has five regions of electron density, which includes three bonding pairs and two lone pairs.
