Final answer:
Non-bonding pairs of electrons in COCl₂ are represented as COCl₂⁻. Therefore, the correct option is c) COCl₂⁻.
Step-by-step explanation:
Non-bonding pairs of electrons in COCl2 are represented as: c) COCl2⁻
In COCl2, the central atom is carbon (C), and it forms single bonds with both oxygen (O) and chlorine (Cl). The Lewis dot diagram for COCl2 can be represented as: 0:C:0, where the two dots (: ) represent the non-bonding pairs of electrons on the oxygen atoms. The negative charge sign (⁻) represents these non-bonding pairs of electrons.
