Question

Which hydrogen bond is stronger intermolecular or intramolecular?

Answer 1

Hint : To answer this question, we first need to understand what chemical bond. A chemical bond is a long-term attraction between atoms, ions, or molecules that allows chemical compounds to form. Ionic bonds are formed by the electrostatic force of attraction between oppositely charged ions, while covalent bonds are formed by the sharing of electrons.

Complete Step By Step Answer:
Hydrogen bond – A hydrogen bond is an electrical attraction between a hydrogen (H) atom covalently bonded to a more electronegative atom or group and another electronegative atom bearing a single pair of electrons (the hydrogen bond acceptor) (Ac). Hydrogen bonds are responsible for binding materials such as paper and felted wool together, as well as causing distinct sheets of paper to adhere together after becoming wet and drying. The solid line represents a polar covalent link, while the dotted or dashed line represents a hydrogen bond.
Intramolecular H-bonding - Any force that binds together the atoms that make up a molecule or compound is known as an intramolecular force (or fundamental force). This is not to be confused with intermolecular forces, which are the forces that exist between molecules. The name's slight difference stems from English's Latin roots, where inter means between or among and intra means inside. Intramolecular forces, for example, are defined as chemical bonding. These forces are frequently stronger than intermolecular forces, which exist between unbonded atoms or molecules.
Intermolecular H-bonding - Intermolecular forces (or secondary forces) are the forces that mediate interactions between molecules, such as forces of attraction or repulsion between atoms and other types of nearby particles, such as atoms or ions. In comparison to intramolecular forces, which hold a molecule together, intermolecular forces are weak. For example, the covalent connection, which involves atoms sharing electron pairs, is substantially stronger than the forces that exist between molecules. Both types of forces are important components of force fields in molecular mechanics.
So, we conclude that, because intramolecular hydrogen bonding involves the actual sharing of electrons, intramolecular forces are stronger. The molecule creating intramolecular hydrogen bonding has two groups, one of which comprises hydrogen atoms linked to the extremely electronegative atom.
So, the final answer is Intramolecular H-bonding.

Note :
Chemical bonds come in a variety of strengths; there are "strong bonds" or "primary bonds" like covalent, ionic, and metallic connections, as well as "weak bonds" or "secondary bonds" like dipole–dipole interactions, the London dispersion force, and hydrogen bonding.
