Question

what is covalent bond, explain its type with
Example​

Answer 1

Answer:

It is a type of bond formed when the atoms of same or different elements combine by mutual sharing of electrons.  Example: Formation of single covalent bond in chlorine molecule: Single covalent bond is formed by sharing one pair of electrons between two atoms.

Answer 2

Answer:

A covalent bond is formed by equal sharing of electrons from both the participating atoms. The pair of electrons participating in this type of bonding is called shared pair or bonding pair. The covalent bonds are also termed as molecular bonds.

Types of Covalent Bonds

• Single Bond: Hydrogen Molecule Hydrogen atom has only one electron in its outermost shell, and requires one more electron to acquire the nearest noble gas configuration of helium (He:1s2). To do so, two hydrogen atoms contribute one electron each to share one pair of electrons between them. This leads to the formation of a single covalent bond between the two hydrogen atoms.
• Double Bond: Oxygen Molecule An oxygen atom has six electrons in its valence shell. As a result, it requires 2 more electrons to achieve the nearest noble gas configuration. When two oxygen atoms share two pairs of electrons this is achieved.
• Triple Bond: Nitrogen Molecule Nitrogen atom has five electrons in its valence shell. It requires three more electrons to acquire a stable configuration of the nearest noble gas (neon). This is done by mutually sharing three pairs of electrons.
