weakest to strongest: they are in this order:
London dispersion, dipole-dipole, hydrogen bonding, ionic
In C6H14 (hexane) and H2O (water), there are London dispersion forces, dipole-dipole interactions, and hydrogen bonding. In HCHO (formaldehyde), there are dipole-dipole interactions and London dispersion forces. In C6H5OH (phenol), there are hydrogen bonding, dipole-dipole interactions, and London dispersion forces.
Hydrogen bonds are stronger than dipole-dipole interactions. Hydrogen bonds occur when a hydrogen atom is bonded to a highly electronegative atom like oxygen, nitrogen, or fluorine, leading to significant electrostatic attraction. Dipole-dipole interactions involve interactions between the partially positive and negative ends of polar molecules.
Hydrogen bonds are stronger than dipole-dipole interactions and London dispersion forces. They involve an electrostatic attraction between a hydrogen atom bonded to an electronegative atom and another electronegative atom. This creates a partial positive charge on the hydrogen and a partial negative charge on the other atom, resulting in a relatively strong bond.
The intermolecular forces present in C2H5OH (ethyl alcohol) are hydrogen bonding, dipole-dipole interactions, and London dispersion forces. Hydrogen bonding occurs between the hydrogen atom of one alcohol molecule and the oxygen atom of another alcohol molecule. Dipole-dipole interactions arise due to the polar nature of the molecule, while London dispersion forces occur as temporary induced dipoles.
The types of van der Waals forces are dispersion forces (London forces), dipole-dipole interactions, and hydrogen bonding. Dispersion forces occur between all molecules and are temporary fluctuations in electron distribution. Dipole-dipole interactions involve permanent dipoles in molecules attracting each other, while hydrogen bonding is a strong dipole-dipole interaction between a hydrogen atom and a highly electronegative atom like oxygen or nitrogen.

In CH3CH2NH2 (ethylamine), the primary forces present are hydrogen bonding, dipole-dipole interactions, and London dispersion forces. The nitrogen atom in the amine group can form hydrogen bonds with hydrogen atoms of other molecules due to its electronegativity, leading to stronger intermolecular interactions. Additionally, the polar C-N bond contributes to dipole-dipole interactions. London dispersion forces are also present but are generally weaker compared to hydrogen bonds and dipole-dipole interactions.

Hydrogen sulfide (HSSH) exhibits London dispersion forces due to temporary dipoles formed by the movement of electrons. It also experiences dipole-dipole interactions because of the difference in electronegativity between sulfur and hydrogen. Additionally, HSSH can engage in hydrogen bonding between the hydrogen atom of one molecule and the sulfur atom of another molecule.

The intermolecular forces present in hydrogen iodide (HI) are dipole-dipole interactions and London dispersion forces. In HI, the hydrogen is partially positive while the iodine is partially negative, leading to dipole-dipole interactions. Additionally, the nonpolar nature of the HI molecule allows for the presence of London dispersion forces.
Yes
London dispersion force usually pertains to carbon carbon chains. It is a very weak force. For polar molecules the intermolecular force is described as dipole-dipole. Oxygen has a greater electronegativity than sulfur so its dipole-dipole force would be stronger than hydrogen sulfide. Oxygen also has the ability to hydrogen bond which is a pretty strong force.
The strongest intermolecular force is hydrogen bonding. It is a type of dipole-dipole interaction that occurs when hydrogen is directly bonded to highly electronegative elements like oxygen, nitrogen, or fluorine. Hydrogen bonding is significantly stronger than other intermolecular forces such as London dispersion forces and dipole-dipole interactions.
The intermolecular forces of formaldehyde (H2CO) are mainly dipole-dipole interactions and London dispersion forces. Formaldehyde has a permanent dipole moment due to the difference in electronegativity between the carbon and oxygen atoms, leading to dipole-dipole interactions. Additionally, London dispersion forces also play a role in holding formaldehyde molecules together.
