In reality, there are three kinds of bonds between adjacent atoms: ionic, covalent, and metallic, as shown in the figure below. The force of attraction between atoms in metals, such as copper and aluminum, or alloys, such as brass and bronze, are metallic bonds. Molecular, ionic, and covalent solids all have one thing in common.

What types of intermolecular forces exist between HI and H2S? asked Sep 11, 2016 in Chemistry by PickardPop. A) dipole-dipole and ion-dipole
Due to this the strongest intermolecular forces between NH3 and H2O are hydrogen bonds. C is not electronegative enough to form hydrogen bonds, due to it having a larger atomic radius than both N and O. Also CH4 molecules cannot have permenant dipole-dipole attractions because each of the species bonded to the carbon is identical and CH4 has a tetrahedral shape.
Feb 13, 2015 · If yes, then this type of intermolecular forces would resemble (but not identical, by definition, to) the permanent dipole-dipole forces in water. In other words, the cause of these intermolecular forces is not an induced temporary dipole in neighboring molecules. Any contribution is appreciated.

A. lowest: H2S, H2Se, H2Te, H2O (the first three are all dipole-dipole and LDF, but their closeness in electronegativity means that the increasing molar mass makes the larger ones have a higher LDF forces and a higher meting point; H-bonding in water makes it highest), intermolecular forces are being broken when these substances melt.
intermolecular forces. • Intermolecular Force (IMF): between molecules. This is the force that holds molecules together. It is a form of “stickiness” between molecules. Examples of intermolecular forces are London dispersion forces (LDF), dipole-dipole forces (DDF), and hydrogen bridging forces (HBF). When we use the word “force” we are referring to intermolecular forces.
Ionic bonds, like those in table salt (NaCl), are due to electrostatic attractive forces between their positive (Na+) and negative charged (Cl-) ions. In unit two, we compared atoms to puppies and electrons to bones in our analogy of how bonding works.
The most polar bond is expected to occur between atoms with the greatest electronegativity difference. Note that Ge, Se and Br are all in period 4. The electronegativities of the atoms follow the expected The geometry of H2O is bent with an unsymmetric charge distribution. Therefore this molecule is polar.

INTERMOLECULAR FORCES Intermolecular forces- forces of attraction and repulsion between molecules that hold molecules, ions, and atoms together. Intramolecular - forces of chemical bonds within a molecule.
London dispersion forces, which result from short-lived dipoles induced by fluctuations in the electron shell of molecules, are also present. They are responsible for the weak interactions between the alkyl chains, like in other alkanes and non-polar molecules.
