Question

What is hydrogen bonding and what are the factors affecting it

Answer 1

The hydrogen bond is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X–H in which X is more electronegative than H, and an atom or a group of atoms in the same or a different molecule, in which there is evidence of bond formation.

A hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen (H) atom, covalently bound to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), experiences the electrostatic field of another highly electronegative atom nearby.

Hydrogen bonds can occur between molecules (intermolecular) or within different parts of a single molecule (intramolecular).

1. concentrations.
2. electronegative of the element.
3. number of hydrogen atoms present in the compound.
4. size of the compound under going hydrogen bonding.

these are the basic factors affect hydrogen bonding.
