Question

Write a note on hydrogen bonding.

Answer 1

Hydrogen bonding:

• The established order of hydrogen bonds, which can be a type of appealing intermolecular force, is known as hydrogen bonding.
• Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom.
• In water molecules, for example, hydrogen is covalent hydrogen bonded to the greater electronegative oxygen atom.

Hydrogen Bonding Conditions:

• In order for the molecule to function, an incredibly electronegative atom ought to be linked to the hydrogen atom. The molecule will become more and more polarized as its electronegativity increases.
• The electronegative atom needs to be small. The smaller the size, the more potent the electrostatic attraction

Types of hydrogen bonding

• Intermolecular hydrogen bonding:-It is formed between two different molecules of the same or different compounds.
• Intramolecular hydrogen bonding:-It is formed when a hydrogen atom is in between the two highly electronegative (F, O, N) atoms present within the same molecule.
