Question

Write the lewis structure for ch2clcoo−. assign a formal charge for any atom with a non-zero formal charge.

Answer 1

The Lewis structure of Chloroacetate (H₂CClCO₂) is given below. In structure it is shown that carbon has a double bond with one oxygen atom and two single bonds with CH₂Cl and O⁻.

Formal Charge;
                        Formal charge is caculated as,

Formal charge  =  # of valence e⁻ - [# of lone pair of e⁻ + 1/2 # of bonded e⁻]

Formal charge on Oxygen (Highlighted Red);

Formal charge  =  6 - [ 6 + 2/2]

Formal charge  =  6 - [6 + 1]

Formal charge  =  6 - [7]

Formal charge  =  -1

Answer 2

Lewis dot structures are the diagrammatic representation of the valence shell electron in a molecule. It also tells the number of bonds and shape of the molecule. The formal charge on oxygen is -1.

Lewis structure of the chloroacetate is attached below.

The structure of chloroacetate represents the six sigma bonds and one pi bond. The structure represents the number of lone pairs present on the chlorine atom and oxygen atom.

A formal charge is assigned to an atom in a compound to understand the sharing of electrons in the given compound or molecule.

Formal Charge is calculated as:

• Formal charge = Number of Valence electrons - [ Number of lone pairs of electrons + $\dfrac {1}{2}$ number of bonded electrons

Formal charge on the oxygen atom:

• Formal charge = 6 - [6 + $\dfrac {2}{2}$]
• Formal charge = 6 - [ 6 +1]
• Formal charge = 6 - [7]
• Formal charge = -1

Therefore, the formal charge of the oxygen in chloroacetate is -1.
