Intermolecular Forces in O2

The video tutorial explores the intermolecular forces in diatomic oxygen (O2). It begins by confirming the absence of ions in O2 due to the lack of charge. The video then examines the Lewis structure of O2, highlighting its non-polar nature due to identical oxygen atoms with no difference in electronegativity. Consequently, O2 exhibits London dispersion forces, a type of van der Waals force characterized by temporary dipoles. These weak forces allow O2 to condense into a liquid at low temperatures. The tutorial concludes by affirming that London dispersion forces are the only intermolecular forces present in O2.

What is the first step in determining the intermolecular forces present in O2?

• Analyzing the boiling point

• Measuring the density

• Checking for the presence of ions

• Examining the color of the gas

Why are ions not present in diatomic oxygen (O2)?

• Because it has a negative charge

• Because it has a positive charge

• Because it is a metal

• Because it lacks any charge

What does the Lewis structure of O2 reveal about its polarity?

• It contains ions

• It has a triple bond

• It is a non-polar molecule

• It is a polar molecule

What is the significance of having two identical oxygen atoms in O2?

• It causes O2 to be an ionic compound

• It makes O2 a polar molecule

• It results in a difference in electronegativity

• It makes O2 a non-polar molecule

Which intermolecular force is present in O2?
