Draw the lewis structure (including resonance structures) for the acetate ion (ch3coo−). for each resonance structure, assign formal charges to all atoms that have formal charge.

Explanation:

Lewis structure : These are the electron dot structure which shows the bonding between the atoms of the molecule and lone pairs of electron(if present on an atom)

Resonance structures : These are the structure which shows the delocalizing of electrons in a molecule. When the molecule have more than one Lewis structure those structure are known as resonance structure.

Formal charge of ,

V= valence electron around an atom

B = number of bonding electrons

N = number of non bonding electrons

Formal charge of structure(I)

Formal charge of structure(II)
