Which character of p-orbital determines the geometry of molecules?
Correct answer: D. Directional
- A. Planar
- B. Axial
- C. Non directional
- D. Directional
Explanation
A p-orbital has two lobes like a dumbell and it has a strong directional character. There are three types of p-orbitals depending on the direction of lobes/their orientation in space along either x or y or z axis. When a bond is formed between two atoms by the overlap of two p orbitals or a p-orbital and an s orbital, the direction of the bond depends on the direction of p-orbital. A covalent bond is rigid and directional. The geometry of a molecule depends on the arrangement of the bonds and hence on the orientation of the orbitals involved in bonding.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
