Frequent question: What has the strongest attraction between molecules?

What is the strongest attractive force between particles?

Solid In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. … The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other.

What is the force of attraction between molecules called?

Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ).

What determines the strength of the attraction between molecules?

To determine strength of attractive forces between the molecules the size of the molecules, their polarity (dipole moment), and their shape. … If two molecules have about the same size and similar shape, the dipole-dipole intermolecular attractive force increases with increasing polarity.

Which substance has the greatest intermolecular forces of attraction between molecules?

The strongest intermolecular force is hydrogen bonding, which is a particular subset of dipole-dipole interactions that occur when a hydrogen is in close proximity (bound to) a highly electronegative element (namely oxygen, nitrogen, or fluorine).

Which form of attraction exists between hydrocarbon molecules?

Hydrocarbons have very weak intermolecular forces called dispersion forces. Intermolecular forces hold molecules together.

Is the attraction between molecules of different substances?

The attraction among molecules of a substance is called cohesion. … The attraction among molecules of different substances is called adhesion.

Is adhesion stronger than cohesion?

Since water forms a concave up meniscus, the adhesion of the molecules to the glass is stronger than the cohesion among the molecules. However, in the absence of the adhesive force (when water reaches the tip of the glass), the cohesive force remains present.

Which of the following has highest intermolecular force of attraction?

Solids have the highest intermolecular forces of attraction. Solid CO2 is a solid. The force of attraction is also known as cohesive force.

When molecules have weak intermolecular forces of attraction?

All atoms and molecules have a weak attraction for one another, known as van der Waals attraction. This attractive force has its origin in the electrostatic attraction of the electrons of one molecule or atom for the nuclei of another, and has been called London dispersion force.
