GENERAL KNOWLEDGE

Detailed explanation-1: -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.

Detailed explanation-2: -Definition: A covalent bond is formed when the valence electrons from one atom are shared between two or more particular atoms. Example: Many compounds have covalent bonding, such as polymers.

Detailed explanation-3: -Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is the lowest energy state of the atom.

Detailed explanation-4: -Answer (B) Double covalent bond. A Double covalent bond is formed when two pairs of electrons are shared between the atoms rather than just one pair.

Detailed explanation-5: -A single covalent bond is formed when two electrons are shared between the same two atoms, one electron from each atom.
