can you explain these bonds with their respective definitions.-
Ionic bond: Ionic bond is when the electron/s of an element which has low ionization energy released to form a positively charged ion and its electron/s are accepted by an element with electron affinity which is positive. Both the ions achieve a more stable configuration. The bond between the cation and anion is based on electrostatic forces of attraction and is called ionic bond.
Covalent bond: When a pair of electrons are shared between elements, the bond is called covalent bond. The sharing of electrons help the elements in the bond is to increase stability of the elements by helping them gain a more stable electronic configuration or a complete outer shell.
Dative bond or Coordinate bond: It is a type of covalent bond in which electrons for the bond are provided by one element only and not by both the elements.
Hydrogen bonding: It is an electromagnetic attractive interaction between a strong electronegative element and a polar hydrogen atom. The electronegative element is generally oxygen, nitrogen or fluorine. This force of attraction can occur between two molecules or between the two elements of the same element.
Van der Waals interaction: Van der Waal's interaction can be of attraction or repulsion. This attraction is separate from the above mentioned bonds and interactions. Van der Waal's interaction occurs between two dipoles. These dipoles can be between two permanent dipoles, or between two induced dipoles or between an induced dipole and a permanent dipole.
