To determine the strongest intermolecular forces in a substance, one can look at the types of molecules present and consider factors such as molecular size, polarity, and hydrogen bonding. Larger molecules with more polar bonds and the ability to form hydrogen bonds tend to have stronger intermolecular forces.
To determine the strongest intermolecular force in a substance, you need to consider the types of molecules present. Look for hydrogen bonding, which is the strongest intermolecular force. If hydrogen bonding is not present, then consider dipole-dipole interactions and London dispersion forces in determining the strength of intermolecular forces.
The strongest intermolecular force present in hydrogen bromide (HBr) is dipole-dipole interaction.
The strongest intermolecular interactions present in diethyl ether are dipole-dipole interactions and London dispersion forces.
A vacuum is present between inter-molecular spaces.
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 phase of a substance is determined by its temperature and pressure, as well as the intermolecular forces present within the substance. Changes in temperature and pressure can cause a substance to transition between solid, liquid, and gas phases.

The strongest intermolecular force in ammonia is hydrogen bonding. This occurs because the nitrogen atom in ammonia can form a hydrogen bond with a hydrogen atom from another ammonia molecule, resulting in a relatively strong attraction between the molecules.
It is because the intermolecular forces(the attractive forces between the molecules of a substance) differ from one substance to another. The chemical with the stronger intermolecular forces will have higher melting and boiling points, and vice versa. This is because more energy is required to separate the molecules to melt or boil the substance, if the forces are strong. The factors that determine the size of these forces are :the type of bonding in the molcules, andthe mass of the molecules.
The strength of the intermolecular forces will determine what phase the substance is in at any given temperature and pressure. Consider the halogens for example, fluorine and chlorine are gases, while bromine is a liquid and iodine is a solid at room temperature. When considering the intermolecular forces present, each of these substances only has London forces, which increase in magnitude with increasing size of the molecules, and size increases as you go down a group in the periodic table. So, fluorine has the smallest intermolecular forces, and iodine has the largest. This explains why these different substances exist in different phases when at room temperature and pressure. The molecules in fluorine, for example, are only slightly attracted to each other, and therefore the substance exists as a gas. The stronger intermolecular forces in bromine, however, hold the molecules close to each other, but not quite strongly enough to prevent the molecules from sliding past each other; this makes bromine a liquid. Finally, in iodine, the intermolecular forces are actually strong enough that the molecules are held in fixed positions relative to each other, thus making iodine a solid.
No, it is not always possible to determine if a substance is pure just by its appearance. Impurities can be present in small amounts and may not be visible to the naked eye. Chemical analysis is typically needed to accurately determine the purity of a substance.
Observation alone is usually not enough to determine the type of bond a substance has. Additional experiments and analysis, such as spectroscopy or crystallography, are often needed to accurately determine the type of bond present in a substance.
The strongest intermolecular force present in ibuprofen is dipole-dipole interactions. Ibuprofen contains polar covalent bonds due to the differences in electronegativity between the atoms, leading to the formation of partial positive and negative charges. These partial charges allow ibuprofen molecules to attract each other through dipole-dipole interactions.
