A hydrogen bond is the electromagnetic attractive interaction of a hydrogen atom and an electronegative atom, such as nitrogen, oxygen or fluorine, that comes from another molecule or chemical group.
covalent bonding between nitrogen and hydrogen atoms
Hydrogen bonding typically results in a decrease in the vibrational frequencies of the involved bonds in IR spectroscopy. This is because hydrogen bonding leads to a stronger bond, which requires more energy to vibrate. As a result, the stretching or bending frequencies of the bonds involved in hydrogen bonding are shifted to lower values in the IR spectrum compared to the same bonds without hydrogen bonding.
Hydrogen bonding can also occur in compounds that contain fluorine, nitrogen, or oxygen atoms. This includes compounds such as alcohols, amines, and carboxylic acids. These molecules have hydrogen atoms bonded to highly electronegative atoms that can attract electron density, resulting in hydrogen bonding interactions.
Hydrogen bonding, ionic bonding, dipole-dipole interactions or van der Waals interaction.
When lone pair of nitrogen becomes involved in resonance process (deloclization) the aromatic ring acquires the negative charge so it is also a negative pole for partially positive hydrogen of other molecule and when lone pair is on nitrogen then hydrogen bonding is also possible, it may be said that it is deloclized hydrogen bonding among the molecules.
Fluorine, Nitrogen and Oxygen because they are highly electronegative and very small. Hope that helps - it is the correct answer to my chemistry homework on WileyPLUS to this exact same question.

The weakest type of bond is a hydrogen bond, which is involved in the bonding of water molecules. Hydrogen bonds form between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another water molecule.

Yes, hydrogen fluoride does exhibit hydrogen bonding.

Hydrogen has one core electron. Core electrons are those in the inner energy levels of an atom and are not involved in chemical bonding.
Yes, water is capable of hydrogen bonding.
No, CF3H (trifluoromethane) does not have hydrogen bonding because hydrogen bonding requires a hydrogen atom bonded to a highly electronegative element like oxygen, nitrogen, or fluorine. In CF3H, the hydrogen atom is not bonded to a highly electronegative element.
