Hydrogen bromide (HBr) is a polar covalent molecule, rather than an ion. Therefore, the intermolecular forces between HBr molecules are primarily dipole-dipole interactions.
Ion dipole
The intermolecular force present in HBr is dipole-dipole interaction. This occurs due to the electronegativity difference between hydrogen and bromine, causing a permanent dipole moment in the molecule that results in intermolecular attractions between neighboring HBr molecules.
HBr primarily exhibits dipole-dipole interactions due to the polarity of the H-Br bond. Additionally, HBr can also experience dispersion forces, caused by temporary dipoles that occur in all molecules.
The intermolecular force in ClF, a molecule of chlorine monofluoride, is dipole-dipole attraction. This force results from the difference in electronegativity between the chlorine and fluorine atoms, causing a partial negative charge on the fluorine atom and a partial positive charge on the chlorine atom, leading to attraction between the molecules.
Stronger intermolecular forces result in higher boiling points because they require more energy to overcome and separate the molecules within a substance. Examples of strong intermolecular forces include hydrogen bonding, dipole-dipole interactions, and ion-ion interactions.

No, since its a polar compound its also considered to be polar. Therefore, it has dipole-dipole forces

The intermolecular force for H2S is dipole-dipole interaction. Since H2S is a polar molecule with a bent molecular geometry, it experiences dipole-dipole forces between the slightly positive hydrogen atoms and the slightly negative sulfur atom.
A hydrogen bond is weaker than a covalent bond. An ion interaction, which involves the attraction between charged particles, can potentially be weaker or stronger than a hydrogen bond depending on the specific ions involved.
No, covalent bonds are intramolecular forces that hold atoms together within a molecule. Intermolecular forces are interactions between molecules that are weaker than covalent bonds, such as hydrogen bonding, dipole-dipole interactions, and van der Waals forces.
In a liquid sample of HBr, you would expect to find predominantly dipole-dipole interactions and some hydrogen bonding. Hydrogen bonding occurs between the hydrogen atom of one molecule and the lone pair of electrons on the bromine atom of another molecule in HBr.
There is no hydrogen bonding in HBr and HI. The intermolecular forces are London dispersion forces- HI has more electrons, so more instantaneous induced dipole-dipole interaction- more intermolecular force- and therefore a higher boiling point.
Helium is a noble gas, so it exhibits weak dispersion forces, also known as London dispersion forces, as its primary intermolecular force. These forces arise from temporary fluctuations in electron distribution around the atom.
