A Possible Lewis Structure for BeCl₂ Is Given Below

A possible Lewis structure for BeCl₂ is given below. Why does this resonance form contribute very little to the true electronic structure for this molecule?

A) It does not use the proper number of valence electrons.
B) It does not obey the octet rule for Beryllium.
C) It does not obey the octet rule for Chlorine.
D) The formal charge of the Beryllium atom is +2 and the formal charge of each Chlorine atom is - 1. This provides a charge separated compound.
E) The formal charge of the Beryllium atom is - 2 and the formal charge of each Chlorine atom is +1. This places a negative charge on a metal and a positive charge on a highly electronegative non-metal atom.
