Detailed explanation-1: -Double bond is a type of chemical bond in which four electrons are shared between two atoms in a molecule. In a double bond two pairs of electrons (four electrons) are shared between two atoms. Example: Formation of Oxygen molecule.

Detailed explanation-2: -A Double bond is when two atoms share two pairs of electrons with each other.

Detailed explanation-3: -4 shared electrons will form a double bond.

Detailed explanation-4: -Atoms bond by sharing electrons. In a typical bond two electrons are shared, one from each of the atoms involved. Carbon has four such sharable electrons of its own, so it tends to form four bonds to other atoms.

Detailed explanation-5: -S = N-A. S = shared electrons : total number of electrons that will be shared and therefore are the bonding electrons. Divide “S” by 2 and you’ll have the number of bonds (lines) in the structure.
