Single Bond, Double Bond and Triple Bond

Single Bond
  • A covalent bond formed when 2 atoms share a pair of electron
  • Represent by dash (-) between 2 atoms
  • A single bond is made up of a sigma (σ) bond
  • Example: HCl and HF

Double Bond
  • A covalent bond formed when 2 atoms share 2 pairs of electron
  • Represent by double dash (=) between 2 atoms
  • A double bond is made up of sigma bond (σ) and pi bonds (π)
  • Example: O2

Triple Bond
  • A covalent bond formed when 2 atoms share 3 pairs of electron
  • Represent by triple dash (Ξ) between 2 atoms
  • A triple bond is made up of 1 sigma bond (σ) and 2 pi bonds (π)
  • Example: N2
