what is the difference in an ionic bond and ONLY a dispersion force bond?

Solutions

Expert Solution

IONIC BOND: All “ionic” bonds can be considered polar covalent, with varying degrees of ionic character.

It is an electrostatic attraction holding together positively charged metal cations and negatively charged nonmetal anions. eg. NaCl, AlCl₃ etc

Dispersion force bond: The London dispersion force is the weakest intermolecular force. It is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.

This force is sometimes called an induced dipole-induced dipole attraction. These are the attractive forces that cause nonpolar substances to condense to liquids and to freeze into solids when the temperature is lowered sufficiently. Because of the constant motion of the electrons, an atom or molecule can develop a temporary (instantaneous) dipole when its electrons are distributed unsymmetrically about the nucleus.

Dispersion forces are present between all molecules, whether they are polar or nonpolar.

the difference between a nonpolar covalent bond, a polar covalent bond, and an ionic bond. Choose the BEST answer: A.Ionic bonds can be considered as 100% polarized toward the metal. B.Polar covalent bonds display partial polarization toward the nonmetal, while ionic bonds exhibit full polarization. C.Nonpolar covalent bonds involve full/equal sharing of electrons, while polar covalent and ionic do not. D.These three types of bonds are part of a continuum that is affected the average electronegativity of the bonded atoms.

Question 21 What is the fundamental difference between covalent and ionic bonding? In a covalent bond, the partners share a pair of electrons; in an ionic bond, one partner accepts electrons from the other. Covalent bonds form between atoms of the same element; ionic bonds form between atoms of different elements. Covalent bonding involves only the outermost electron shell; ionic bonding also involves the next electron shell inside the outermost shell. In covalent bonding, both partners end up with filled...
