What else can I help you with?
Do London dispersion forces act only in solids?
No, London dispersion forces can act in solids, liquids, and gases. These weak intermolecular forces arise from temporary fluctuations in electron distribution and are present in all types of matter.
Which molecular solid would have the lowest boiling point?
One with induced dipole attractions
What usually has lower melting points than ionic solids?
Molecular solids
Do simple molecular substances have high or low melting and boiling points?
Simple molecular substances typically have low melting and boiling points. This is because the weak intermolecular forces, such as London dispersion forces, in simple molecular substances are easily overcome compared to the stronger bonds in ionic or metallic substances.
What kind of solid tends to have the lowest melting points?
Molecular compounds tend to have the lowest melting points.
What force holds molecular solids together?
London dispersion forces (also known as van der Waals forces) hold molecular solids together. or Intermolecular forces

Which molecular solid would have the lowest boiling point?
One with induced dipole attractions
Are molecules that have only London dispersion forces always gases at room temp?
No, molecules that primarily have only London dispersion forces are not always gases at room temperature. The physical state of a substance at room temperature depends on its molecular weight and the strength of these dispersion forces. Larger molecules with stronger dispersion forces can be liquids or solids, while smaller ones may be gases. For example, noble gases like argon are gases, while larger hydrocarbons like octane are liquids at room temperature.

Molecular compounds tend to have the lowest melting points.
What is one type of attractive force that stabilizes molecular solids?
One type of attractive force that stabilizes molecular solids is the van der Waals force. This force arises from temporary dipoles induced in molecules due to fluctuations in electron distribution, leading to weak intermolecular interactions that help hold the molecules together in the solid state.
What molecular solid would have the lowest boiling point?
A. One with induced dipole attractions B. One that has hydrogen bonding C. One with dipole-dipole attractions D. One made of polar molecules C. One with dipole-dipole attractions - The molecular solids would have the lowest boiling point because of WEAK INTERMOLECULAR FORCES.
What kind of solids are iodine and naphthalene?
Iodine is a molecular solid composed of diatomic molecules of I2, held together by weak van der Waals forces. Naphthalene is a covalent molecular solid made of individual naphthalene molecules held together by London dispersion forces.
Which intermolecular force is present is present in solids and liquids that are composed of non polar molecules?
London dispersion forces (instananeous dipole - induced dipole interactions)
