Question:
What are electron deficient compounds? Are BCl₃ and SiCl₄electron deficient species? Explain.

Answer:

In an electron-deficient compound, the octet of electrons is not complete, i.e., the central metal atom has an incomplete octet. Therefore, it needs electrons to complete its octet.

(i) BCl₃

BCl₃ is an appropriate example of an electron-deficient compound. B has 3 valence electrons. After forming three covalent bonds with chlorine, number of electrons around it increases to 6. However, it still lacks two electrons to complete its octet.

(ii) SiCl₄

The electronic configuration of silicon is ns² np². This indicates that it has four valence electrons. After it forms four covalent bonds with four chlorine atoms, its electron count increases to eight. Thus, SiCl₄ is not an electron-deficient compound.
