sigma bond represents a single weak chemical bond.
which type of bond represents a single weak chemical bond?
sigma bond
a double bond has two shared pairs of electrons, one in a sigma bond and one in a pi bond with electron density concentrated on two opposite sides of the internuclear axis. a triple bond consists of three shared electron pairs, forming one sigma and two pi bonds. an example is nitrogen. quadruple and higher bonds are very rare and occur only between certain transition metal atoms.

a chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. the bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. the strength of chemical bonds varies considerably; there are "strong bonds" or "primary bonds" such as covalent, ionic and metallic bonds, and "weak bonds" or "secondary bonds" such as dipole–dipole interactions, the london dispersion force and hydrogen bonding.
