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.
A hydrogen bond is a very strong dipole-dipole bond. A hydrogen bond can only form between hydrogen and a strong electromagnetic atom; fluorine, oxygen or chlorine.
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.
An ion-dipole bond is a type of intermolecular force that forms between an ion and a polar molecule. The positive or negative charge on the ion interacts with the partial positive or negative charge on the polar molecule, resulting in attraction between the two species. This type of bond is important in solutions where ions are present alongside polar molecules.
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.
Polar diatomic molecules are made of two different atoms joined by a covalent bond. This bond results in an uneven distribution of electrons, leading to a separation of charge and the development of a dipole moment.
The bond dipole moment measure the polarity of a chemical bond.
Hydrogen bond < Van der Waals < Dipole-dipole < Ionic bond < Covalent bond Van der Waals < Hydrogen bond < Dipole-dipole < Covalent bond < Ionic bond Hydrogen bond < Van der Waals < Dipole-dipole < Covalent bond < Ionic bond The correct order is option 3: Hydrogen bond < Van der Waals < Dipole-dipole < Covalent bond < Ionic bond.
A covalent bond is stronger than a dipole-dipole attraction. In a covalent bond, atoms share electrons to create a strong bond between them, while in a dipole-dipole attraction, molecules with polar bonds are attracted to each other due to their partial charges.

Yes, a molecule can exhibit bond dipole moments if there is a difference in electronegativity between the atoms that make up the bond. However, if these bond dipole moments are arranged symmetrically and cancel each other out, the molecule will not have a net molecular dipole moment.
To calculate the dipole moment of a molecule, you need to determine the magnitude and direction of the individual bond dipoles within the molecule. The dipole moment is the vector sum of these bond dipoles. It is calculated by multiplying the magnitude of each bond dipole by the distance between the charges and then adding up all the individual bond dipole moments to get the total dipole moment of the molecule.
In pure water, the primary intermolecular force is a hydrogen bond, which is a specific type of dipole-dipole intermolecular force with notably more energy than most dipole-dipole intermolecular forces.
Yes, O2 is not a dipole-dipole molecule because it is a diatomic molecule with a nonpolar covalent bond.
