Intermolecular forces are the forces between molecules which hold two or more of them together; intramolecular forces happen inside of the molecule, & are the forces holding the atoms together witch form the molecule.
Hydrogen bonding is a type of intermolecular force of attractionAdded:This is between molecules.It is not as strong as chemical bonding within molecules (intramolecular) though.
AlH3 alane is a covalent solid and is a giant molecule, so no intermolecular forces will be present. Planar AlH3 molecules have been isolated at very low temperatures. AlH3 molecules would be predicted to have no dipole moment due to their shape. The only intermolecular forces would be London dispersion forces.
In a single molecule of CH4 you would have intramolecular forces that are covalent bonds. The intermolecular forces that exist between molecules of CH4 are called dispersion forces. These forces are the only intermolecular forces that occur between non-polar molecules.
Yes, CBr4 has a higher boiling point than CCl4 because bromine atoms are larger and heavier than chlorine atoms, leading to stronger van der Waals forces between molecules in CBr4, requiring more energy to break these intermolecular attractions.
Hydrogen bonds are stronger than van der Waals forces. Hydrogen bonds are specifically a type of dipole-dipole interaction that occurs between a hydrogen atom bonded to an electronegative atom and another electronegative atom. Van der Waals forces, on the other hand, include London dispersion forces and dipole-dipole interactions that occur between molecules due to temporary fluctuations in electron distribution.
Intramolecular forces are not intermolecular forces !
A covalent bond is a strong chemical force that results from the sharing of electrons between atoms. It is a type of intramolecular force that holds atoms together within a molecule.

Water (H2O) has stronger intermolecular forces than ammonia (NH3) due to hydrogen bonding in water molecules. Hydrogen bonding is a type of intermolecular force that is stronger than the dipole-dipole interactions present in ammonia molecules.
The type of intermolecular force present in Br2 is London dispersion forces. These forces are the weakest of the intermolecular forces and result from temporary fluctuations in electron distribution around the molecule, leading to a temporary dipole moment.

There are only four ways that substances interact, or if you prefer, four forces in the universe. They are gravity, the weak nuclear force, electro-magnetic, and the strong nuclear force. In molecules ( presumably in liquid or gaseous states ) they will be slightly pulled together by gravity, but it is the electro-magnetic force that governs everything else. Whether they bind together, break down into component atoms or simpler molecules, form new compunds, etc. is all part of the electro-magnetic interaction.
The intermolecular forces in CH4 (methane) are London dispersion forces. Methane molecules are non-polar, so the only type of intermolecular force present is the weak temporary dipole-induced dipole interactions between molecules.
Iron is a metal and does not typically form molecules with strong intermolecular forces. Instead, iron atoms are held together by metallic bonding which is a type of attractive force between metal atoms.
The intermolecular force in AsH3 is dipole-dipole interaction, which occurs between the partial positive charge on the hydrogen atoms and the partial negative charge on the arsenic atom. This force is weaker than hydrogen bonding but stronger than London dispersion forces.
