Is SiCl₄ electron deficient compound. Explain

NO

SiCl4 – In silicon tetrafluoride, silicon has 4 valence electrons. After forming covalent bonds with four chlorine atoms silicon will have 8 valence electrons around it.

Silicon cannot extend its covalency beyond 4, as it does not have‘d’ orbitals. Hence SiCl4 is not an electron deficient compound.
