What is a single bond?

Answer 1

Ruby Allen

A single bond is formed when a pair of electrons is shared between atoms in a covalent bond.

As in the case of #H_2#

And in #F_2#

Sometimes molecules share two pairs in the double bond of #O_2#

And even triple bonds in #N_2#

And sometimes molecules may have several single bonds as is the case with a molecule like #CH_4#
