Problem: Why don't we draw double bonds between the Be atom and the Cl atoms in BeCl  2?a. That would give positive formal charges to the chlorine atoms and a negative formal charge to the beryllium atom.b. There aren't enough electrons.c. That would result in more than eight electrons around beryllium.d. That would result in more than eight electrons around each chloride atom.e. That would result in the formal charges not adding up to zero.

FREE Expert Solution

Analyze the structure of BeCl2 and use the concept of Octet rule exceptions to answer the problem


Step 1. Establish the octet rule exceptions

  • Recall that atoms tend to follow the octet rule which refers to the tendency of atoms to prefer eight electrons in the valence shell.
