Intermolecular Forces in SO3

The video tutorial explores the intermolecular forces in sulfur trioxide (SO3). It begins by determining that SO3 does not have ions and is a non-polar molecule due to its trigonal planar geometry. Consequently, the only intermolecular forces present are London dispersion forces, which are weak and temporary. The video concludes with a mention of additional resources for understanding SO3's polarity and Lewis structure.

What is the first question to consider when determining the intermolecular forces in SO3?

• Is SO3 a solid at room temperature?

• Does SO3 have a high boiling point?

• Is SO3 soluble in water?

• Are there ions present in SO3?

What is the molecular geometry of SO3?

• Bent

• Trigonal planar

• Linear

• Tetrahedral

Why is SO3 considered a non-polar molecule?

• It has a high electronegativity difference.

• It has a symmetrical trigonal planar shape.

• It contains ionic bonds.

• It has a net dipole moment.

Which type of intermolecular force is present in SO3?

• Hydrogen bonding

• Ionic bonding

• Dipole-dipole interactions

• London dispersion forces

What causes London dispersion forces to occur in non-polar molecules like SO3?

• Hydrogen bonds

• Ionic charges

• Permanent dipoles

• Temporary dipoles

Why are London dispersion forces considered weak?

• They are temporary and easily disrupted.

• They involve strong ionic interactions.

• They are only present in solids.

• They require high temperatures to form.
