Question

Hydrogen bond is represented by a___.

Answer 1

Hint : A hydrogen bond informally called as H-bond is an electrostatic force of attraction. This attraction occurs between hydrogen atom which is covalently bonded to a more electronegative group and atom mainly with FON that is fluorine, oxygen, nitrogen which are the three most electronegative elements of all the elements known to us.

Complete Step By Step Answer:
Hydrogen bonds are represented by the H- - -Y system, where these dashed lines represent the hydrogen bonds. When hydrogen bonds are formed then this formation refers to the hydrogen bonding. These hydrogen bonds refers to the special class of attractive intermolecular forces which arises due to the dipole-dipole interaction between a hydrogen atom which is bonded to a highly electronegative atom. There is another highly electronegative atom that lies in the vicinity of the hydrogen atom. For example, in a water molecule the hydrogen atom is linked to the strongly electronegative oxygen atom. Hydrogen atoms develop slightly positive charge and oxygen atoms develop slightly negative charge because the shared pair of electrons are more attached to the oxygen atom.

Note :
Hydrogen bond can be intermolecular as well as intramolecular (within the same molecule) also. Hydrogen bonds are stronger than van der Waals interactions and weaker than fully covalent or ionic bonds. This bond is formed in inorganic molecules like water and organic molecules like DNA and proteins. High boiling point of water is due to the high number of hydrogen bonds formed by each molecule.
