A Possible Lewis Structure for BeCl₂ Is Given Below

question 22

Multiple Choice

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.
