The HBr molecule is linear (obviously, since it contains only two atoms). The dipole moment is a vector, parallel to the bond, pointing toward the partially positively charged atom, which is, in this case, the hydrogen. The magnitude of the dipole moment is the difference in the partial electrical charges on each atom times the spatial separation of the atoms in the bond. In a molcule with more than two atoms (more than one bond), the dipole moment of each bond must be added vectorially and the resultant vector will determine the dipole moment of the molecule. For instance, carbon dioxide has two carbon-oxygen double bonds of high polarity, but because the molecule is linear, and the individual dipoles oppose each other, the carbon dioxide molecule has no net dipole moment.
Hydrogen fluoride has a stronger dipole-dipole interaction than hydrogen chloride. This is because fluorine is more electronegative than chlorine, leading to a larger difference in charge distribution and a stronger dipole moment in hydrogen fluoride.
The main interactions between molecules of hydrogen chloride are dipole-dipole interactions. Hydrogen chloride is a polar molecule with a partially positive hydrogen end and a partially negative chlorine end. These partial charges attract neighboring hydrogen chloride molecules, resulting in dipole-dipole interactions.
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.
The dipole in the nitrogen-hydrogen bond points towards the nitrogen end. The arrow showing a dipole moment points towards the more electron rich region, with its tail at the electron poor region.

Yes, hydrogen bromide exhibits dipole-dipole interactions due to the difference in electronegativity between hydrogen and bromine, creating a permanent dipole moment. This leads to attractive interactions between the partially positive hydrogen atom and the partially negative bromine atom in neighboring molecules.
The strongest intermolecular force present in hydrogen bromide (HBr) is dipole-dipole interaction.
It should be pointed towards the oxygen.
The intermolecular forces (IMF) present in hydrogen bromide (HBr) primarily include dipole-dipole interactions and London dispersion forces. HBr is a polar molecule due to the difference in electronegativity between hydrogen and bromine, leading to a permanent dipole. Additionally, London dispersion forces are present due to temporary dipoles that can occur in all molecules. Overall, the dipole-dipole interactions are the dominant force in HBr.
Hydrogen bromide (HBr) is a polar covalent molecule, rather than an ion. Therefore, the intermolecular forces between HBr molecules are primarily dipole-dipole interactions.
The dipole moment direction for methanol is from the oxygen atom towards the hydrogen atom in the molecule. This is because oxygen is more electronegative than hydrogen, causing an unequal sharing of electrons and creating a partial negative charge on oxygen and a partial positive charge on hydrogen, resulting in a dipole moment.
The direction of the dipole moment for H-F is from the hydrogen atom towards the fluorine atom, following the direction of electron density. This means that the hydrogen atom has a partial positive charge, and the fluorine atom has a partial negative charge.
Yes, HBr is a polar molecule since hydrogen bromide has a significant difference in electronegativity between hydrogen and bromine atoms, causing an uneven distribution of charge leading to a partial positive charge on hydrogen and a partial negative charge on bromine.
Hydrogen fluoride has a stronger dipole-dipole interaction than hydrogen chloride. This is because fluorine is more electronegative than chlorine, leading to a larger difference in charge distribution and a stronger dipole moment in hydrogen fluoride.
The hydrogen bond is not strong.
Yes, water shows all three types of common intermolecular forces, namely dispersion forces, dipole-dipole forces and hydrogen bonds. Dispersion forces are present at any species which consists of movable charges that can be shifted with respect to one another. Thus a dipole emerges which on his part can induce dipoles in close-by molecules. The permanent dipole of water molecules leads to dipole-dipole forces. They can be distinguished from hydrogen bonds as they are present even at angles where no significant hydrogen bonds are expected any more.
The main interactions between molecules of hydrogen chloride are dipole-dipole interactions. Hydrogen chloride is a polar molecule with a partially positive hydrogen end and a partially negative chlorine end. These partial charges attract neighboring hydrogen chloride molecules, resulting in dipole-dipole interactions.
