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).
What phase has the strongest intermolecular forces?
Due to the solid’s low kinetic energy, particles have no “time” to move around, the particles have more “time” to be attracted. Therefore, solids have the strongest intramolecular forces (because they have the strongest attraction).
What are the 3 intermolecular forces from weakest to strongest?
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.
What is the weakest type of intermolecular force?
London dispersion forces, under the category of van der Waal forces: These are the weakest of the intermolecular forces and exist between all types of molecules, whether ionic or covalent—polar or nonpolar. The more electrons a molecule has, the stronger the London dispersion forces are.
Which compound will have the weakest intermolecular forces?
Intermolecular Forces And Stability : Example Question #4
The compound with the highest vapor pressure will have the weakest intermolecular forces. Octane and pentane have only London dispersion forces; ethanol and acetic acid have hydrogen bonding. Hydrogen bonding is much stronger than London dispersion forces.
Which state has the strongest intermolecular forces?
The solid-state has the strongest intermolecular forces of attraction and so their molecules are close to each other.
Which attractive force is the weakest?
Dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond).
Which state of matter has the least intermolecular forces?
The state of matter with the least intermolecular forces of attraction is the gaseous state. The molecules of gases are loosely bounded and are far apart from each other.
Which hydrogen bonding is the strongest?
The strength of hydrogen bond depends upon the coulumbic interaction between the electronegativity of the attached atom and hydrogen. Fluorine is the most electronegative element. F−H−−−F bond will be strongest H bond.
What is the weakest force in chemistry?
The London dispersion force is the weakest intermolecular force. The London dispersion force 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.
What is the strongest intermolecular force in water?
The strongest intermolecular force in water is a special dipole bond called the hydrogen bond. Many molecules are polar and can form bipole-bipole bonds without forming hydrogen bonds or even having hydrogen in their molecule.
Which is the strongest intermolecular force below?
Explanation: Ion-dipole forces are the strongest of the intermolecular forces. Hydrogen bonding is a specific term for a particularly strong dipole-dipole interaction between a hydrogen atom and a very electronegative atom (oxygen, fluorine, or nitrogen).
What are the 4 types of intermolecular forces?
There are four major classes of interactions between molecules and they are all different manifestations of “opposite charges attract”. The four key intermolecular forces are as follows: Ionic bonds > Hydrogen bonding > Van der Waals dipole-dipole interactions > Van der Waals dispersion forces.
What are 3 types of intermolecular forces?
There are three types of intermolecular forces: London dispersion forces (LDF), dipole- dipole interactions, and hydrogen bonding.
