1. Understand Formal Charge
Formal charge is a way to track the distribution of electrons in a molecule and helps us predict the most likely structure. It's calculated as:
* Formal Charge = (Valence Electrons) - (Non-bonding Electrons) - (1/2 Bonding Electrons)
2. Draw the Lewis Structure
* Hydrogen (H): 1 valence electron
* Chlorine (Cl): 7 valence electrons
* Oxygen (O): 6 valence electrons
The Lewis structure of HClO is:
O
||
Cl - H
3. Calculate the Formal Charge of Chlorine
* Valence Electrons (Cl): 7
* Non-bonding Electrons (Cl): 6 (3 lone pairs)
* Bonding Electrons (Cl): 2 (1 single bond with oxygen)
Formal Charge (Cl) = 7 - 6 - (1/2 * 2) = 0
Therefore, the formal charge of chlorine in HClO is 0.
