How to Draw the Lewis Structure for Ozone (and resonance) @wbreslyn

In this video, we walk through how to draw the Lewis structure for ozone (O₃), step by step. We look at how valence electrons are distributed, where the lone pairs go, and how the bonding works between the three oxygen atoms.

Ozone has two possible resonance structures — one with the double bond on the left, and one with the double bond on the right. But the real structure is a resonance hybrid of both. I explain what that means and why it matters when you're trying to understand the molecule’s behavior.

We also talk about molecular geometry, specifically why ozone has a bent shape. Using VSEPR theory, we look at how the lone pairs on the central oxygen push the molecule into this geometry.

$Convert 3 L to mL (3 Liters to Milliliters) To convert 3 liters (L) to milliliters (mL), you can use the following steps. Note that the L will cancel out as you perform the conversion, leaving only mL: Conversion Factor: 1 liter (L) = 1000 milliliters (mL) Start with the quantity you want to convert (3 L) and set up a ratio where the original unit (L) is in the denominator and the target unit (mL) is in the numerator, using the conversion factor: Conversion factor: 1000 mL / 1 L Write the quantity you want to convert (3 L) as a fraction over 1: 3 L / 1 Multiply this fraction by the conversion factor: (3 L / 1) * (1000 mL / 1 L) Notice that the units of liters (L) in the numerator and denominator cancel out, leaving only the units of milliliters (mL): (3 * 1000) / (1 * 1) mL = 3000 / 1 mL = 3000 mL So, 3 L is equivalent to 3000 milliliters. The units of liters cancel out during the conversion process, leaving only milliliters as the final unit.$

$Convert 4.5 L to mL (4.5 Liters to Milliliters) To convert 4.5 liters (L) to milliliters (mL), you can use the following steps. Note that the L will cancel out as you perform the conversion, leaving only mL: Conversion Factor: 1 liter (L) = 1000 milliliters (mL) Start with the quantity you want to convert (4.5 L) and set up a ratio where the original unit (L) is in the denominator and the target unit (mL) is in the numerator, using the conversion factor: Conversion factor: 1000 mL / 1 L Write the quantity you want to convert (4.5 L) as a fraction over 1: 4.5 L / 1 Multiply this fraction by the conversion factor: (4.5 L / 1) * (1000 mL / 1 L) Notice that the units of liters (L) in the numerator and denominator cancel out, leaving only the units of milliliters (mL): (4.5 * 1000) / (1 * 1) mL = 4500 / 1 mL = 4500 mL So, 4.5 L is equivalent to 4500 milliliters. The units of liters cancel out during the conversion process, leaving only milliliters as the final unit.$
