Frequent question: Which has the greatest attraction between molecules?

Which substance has stronger attractions between its molecules?

For molecular substances that contain molecules of about the same size, substances with hydrogen bonds have stronger attractions between the particles than substances with either dipole-dipole attractions or London forces, and substances with dipole-dipole attractions have stronger attractions between the particles …

Which atom has the greatest attraction?

Explanation: Fluorine has the greatest attraction for electrons in any bond that it forms. The attraction of an atom for shared electrons is called its electronegativity.

Why are some molecules more strongly attracted to each other?

In many molecules, the electrons that are shared in a covalent bond are not shared equally among the two atoms in the bond. Typically, one of the atoms attracts the electrons more strongly than the other, leading to an unequal sharing of electrons in the bond. This idea is illustrated in Figure 8.1.

What are the strongest and weakest forces of attraction between molecules?

There are three different types of intermolecular forces in terms of strength. They are (strongest to weakest) hydrogen bonding, dipole-dipole and Van der Waals’ forces. … Van der Waals’ forces are forces of attraction which exist between all atoms and molecules.

Which 4 elements have the highest electronegativity and what does this mean about their attraction for bonded electrons?

Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79). This indicates that fluorine has a high tendency to gain electrons from other elements with lower electronegativities.

Which atom has the greatest attraction for the electrons in a chemical bond oxygen?

in the above group oxygen is most electronegative,so it has the most attraction for the electrons in chemical bonds.

Which type of elements tend to have the greatest attraction for electrons in a bond?

The higher the electronegativity value of an atom, the greater its attraction for bonded electrons. Nonmetals typically have the highest electronegativity values and therefore the greatest attraction for bonded electrons.

Which type of intermolecular attractive force operates between all molecules?

This attractive interaction is called the dispersion force which operates between all atoms, polar and nonpolar molecules. Thus, the forces that operates on all molecules is London dispersion force.

Which force causes attraction between o2 molecules?

hydrogen bond: An intermolecular attraction between a partially positively charged hydrogen in one molecule and a partially negatively charged oxygen, nitrogen, or fluorine in a nearby molecule.

How can you tell which molecule has stronger intermolecular forces?

If the molecules have similar molar masses and similar types of intermolecular forces, look for the one that is the most polar or that has the most electronegative atoms or the most hydrogen bonding groups. That one will have the strongest IMF’s overall.
