Question

what are electron deficient compounds?Is AlCl3 an electron deficient species? Explain ​

Answer 1

Answer:

Yes, aluminium chloride (AlCl3) is electron deficient because if we look at its electronic configuration (1s22s22p63s23p1) it has got only 6 electrons instead of 8 in its outermost or valence shell. ... In the p orbit, 2 orbitals will be vacant making it is electron-deficient compound.

Answer 2

• " The compounds which do not contain any electrons in its valance shell called electron-deficient compounds".
• Yes AlCl3 is an electron-deficient species
• The electronic configuration of Al is
• ${1s}^{2} {2s}^{2} {2p}^{6} {3s}^{2} {3p}^{1}$
• So, its valance shell has three unpaired electrons which are used to make bonds with three chlorine atoms. That's why Al does not contain any electrons in the valance shell and become an electron-deficient compound.
