Which one of the following is electron deficient compounds :
Correct answer: D. BCL3
- A. NH3
- B. PH3
- C. PCL3
- D. BCL3
Explanation
Electron-deficient compounds are those that have fewer electrons than what would be expected based on the octet rule or the number of valence electrons available. These compounds often involve elements from groups 2 and 13 of the periodic table, as they tend to form compounds with incomplete valence shells.

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.
