Answer to Question #90014 in General Chemistry for Jaushua Carmona

Question

types of bonds

Answer 1

Solution.

There are 6 types of chemical bonds: ionic, covalent polar, covalent non-polar, metallic, hydrogen and donor-acceptor.

Ion bonding is characteristic of elements with a large difference in electronegativity, for example, sodium chloride, cesium fluoride.

Covalent polar bond occurs between non-metal atoms with a small difference in electronegativity, such as ammonia, carbon dioxide.

Covalent non-polar bond occurs between the same atoms, as a result, the difference in electronegativity is approximately zero, for example, oxygen, nitrogen, chlorine (halogens, except astatine).

A metallic bond occurs between the atoms of pure metals, for example, copper, sodium.

The hydrogen bond is a type of intermolecular bond between a hydrogen atom and a more electronegative atom (nitrogen, fluorine, oxygen), for example, in water, alcohol, phenol, hydrofluoric acid molecules.

A donor – acceptor bond occurs when one of the atoms has an empty (vacant) orbital, and the other has a lonely pair of electrons. In this case, the first atom is an acceptor, and the second donor. For example, ammonium ion, many coordination compounds, boron tetrafluoride ion.
