Homework Answers
Structure of a molecule can be drawn based on valance of the atoms involved in the structure.
An atom form maximum number of bonds in order to get octet configuration.
Consider the atoms present in the bicarbonate ion; connect them by satisfying their valance. Place the nonbonding electrons and formal charges on the atoms in the structure.
Charge on an atom without considering electronegativity differences is called as formal charge.
Electrons that do not involved in the bond formation are called as non-bonding electrons.
Hydrogen forms one bond with other atoms. Carbon belongs to Group 4A of the periodic table, thus its valance is 4. Oxygen belongs to Group 6A of the periodic table, its valance is 4.
Draw the supposed structure of the bicarbonate ion as shown below.
Correct the bonding on carbon atom by adding formal charges on one of the oxygen atoms.
Structure of the bicarbonate ion is as follows:
