Question

What are electron deficient compounds explain with example?


Open in App
Solution

Electron deficient compounds:

  • Compounds wherein the central atom lacks eight electrons in its outer shell or possesses eight electrons but can widen the valency owing to the existence of unoccupied d – orbitals.
  • In brief, electron-deficient compounds lack enough electrons to fulfill the octet of the central atom.

Examples:

  • Electron-deficient compounds are those with less than 8 electrons in their valence shells, such as B2F6,Al2Cl6, and others.

Boron family example of Electron deficient compounds:

  • Boron, for example, with the electronic structure [He]2s22p1, creates compounds known as electron-deficient compounds.
  • Boron has just three valence electrons, however, four orbitals are available to house these electrons.
  • Other boron family members, such as Aluminum, Gallium, Indium, and Thallium, have a proclivity to lose valence electrons and generate ionic M3+ entities in their compounds.
