Question:

In the vapor phase, BeCl2 exists as a discrete molecule.
(a) Draw the Lewis structure of this molecule, using only single bonds. Does this Lewis structure satisfy the octet rule?
(b) What other resonance structures are possible that satisfy the octet rule?
(c) On the basis of the formal charges, which Lewis structure is expected to be dominant for BeCl2?
