Determine what is wrong with each Lewis structure and write the correct structure.
Here, we are going to determine what is wrong with the given Lewis structures.
The Lewis dot structure provide a picture of bonding in molecules and ions in terms of the shared pairs of electrons and the octet rule. While such a picture may not explain the bonding and behaviour of a molecule completely, it does help in understanding the formation and properties of a molecule to a large extent. Writing of Lewis dot structures of molecules is, therefore, very useful.
