What is the bond angle of a T shaped molecule?
NOTES: This molecule is made up of 5 sp3d hybrid orbitals. Three orbitals are arranged around the equator of the molecule with bond angles of 120o. Two orbitals are arranged along the vertical axis at 90o from the equatorial orbitals.
What are the 4 shapes of molecules?
Lewis Structures and the Shapes of Molecules
| Formula | Shape | |
|---|---|---|
| 1. | CH4 | tetrahedral |
| 2. | NH3 | trigonal pyramidal |
| 3. | H2O | bent |

What are the 5 main molecular shapes?
Molecular Geometries. The VSEPR theory describes five main shapes of simple molecules: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.
How is a T-shaped geometry formed?
According to VSEPR theory, T-shaped geometry results when three ligands and two lone pairs of electrons are bonded to the central atom, written in AXE notation as AX3E2. The three atoms bond at 90° angles on one side of the central atom, producing the T shape.
What is the molecular shape if there are 6 No of electrons?

How do you determine molecular shape?
There are three basic steps to determining the molecular shape of a molecule: Write the Lewis dot structure of the molecule. That gives you the steric number (SN) – the number of bond pairs and lone pairs around the central atom. Use the SN and VSEPR theory to determine the electron pair geometry of the molecule.
What is T – shaped in chemistry?
In chemistry, T-shaped molecular geometry describes the structures of some molecules where a central atom has three ligands. Ordinarily, three-coordinated compounds adopt trigonal planar or pyramidal geometries. Examples of T-shaped molecules are the halogen trifluorides, such as ClF3.
What is the bond angle of T – shaped?
T-shape is a molecular geometry that results when there are 3 bonds and 2 lone pairs around the central atom in the molecule. The atoms bonded to the central atom lie at the ends of a T with 90° angles between them.
What are two theories predict molecular geometry?
• By knowing the number of bonding and nonbonding electron pairs we can predict the shape of the molecule. Two (2) Theories for MOLECULAR GEOMETRY 1. Valence Shell Electron Pair Repulsion (VSEPR) THEORY 2. TheValence Bond (VB) THEORY Lewis Structures & Formal Charge
