a covalent bond that results from the sharing of two pairs of electrons between two atoms
Two atoms sharing electrons as in a single bond (that is, a sigma bond) may also share electrons in an orbital with a node passing through the two atoms. This adds a second, weaker bonding interaction (a pi bond); the combination is termed a double bond. A twisting motion that forces the nodal plane at one atom to become perpendicular to the nodal plane on the other atom eliminates the (signed) overlap between the atomic orbitals, destroying the pi bond. The energy required to do this creates a large barrier to rotation about the bond (see triple bond).
The chemical bond between two carbon atoms can involve one, two or three pairs of electrons, producing a single (C-C), double (C=C) or triple (CºC) bond. While the extra pairs of electrons give the bond more energy they also make it more chemically reactive.
double bond is a combination of a σ and a π bond, caused by overlap of two s orbitals and two p orbitals.
a covalent bond in which two pairs of electrons are shared between two atoms
a and a bond and a triple bond is a and two bonds
a chemical bond caused by the action of two pairs of electrons instead of just one pair
a sigma bond and a pi bond
A type of covalent bond in which a pair of atoms shares two pairs of electrons.
When an atom is bonded to another atom by two sets of electron pairs. Back to .
a bond in which two atoms share two pairs of electrons.
type of linkage between adjacent carbon atoms in a fatty acid, with two linkages, rather than the more normal one link.
Two shared pairs of electrons.
A pair of shared electrons. Atoms at either end cannot rotate around bond. Also called pi bond. Back to .
some atoms can share two pairs of electrons to form a double bond (two covalent bonds). Formally the second (double) bond arises from the overlap of p orbitals from two atoms, already united by a sigma bond, to form a pi bond.
The configuration of two adjacent carbon atoms with dual linkage between the carbons.
A covalent bond in which each of the two atoms in the bond are sharing two electrons. Hence the double bond involves a sharing of four electrons in all. In structural diagrams the double bond is shown as two lines connecting the atoms.
A double bond is a covalent bond resulting from the sharing of four electrons (two pairs) between two atoms. Classifying materials
