Which of the following is tetrahedral?
Correct answer: B. 109.5
- A. 180
- B. 109.5
- C. 120
- D. 90
Explanation
A tetrahedral arrangement has four atoms or groups bonded to a central atom, creating a three-dimensional shape with bond angles of approximately 109.5 degrees. This geometry is commonly found in molecules with four bonding pairs of electrons and no lone pairs, such as methane (CH4) or carbon tetrachloride (CCl4).

About VSEPR Theory
Valence shell electron pair repulsion theory predicts molecular shape by arranging bonding pairs and lone pairs around a central atom to minimize repulsion. Questions cover linear, trigonal planar, tetrahedral, trigonal bipyramidal and octahedral electron geometries, bond angles and distortions caused by lone pairs. Electron geometry is not always the same as molecular shape.
