# How can I draw sigma bonds?

Sigma ($\sigma$) bonds are formed when a $\sigma$ molecular orbital is made, and single bonds contain one $\sigma$ bond; in contrast, pi ($\pi$) bonds, which are formed when $\pi$ molecular orbitals are made, are found in double (one $\sigma$ + one $\pi$ bond) and triple (one $\sigma$ + two $\pi$ bonds) bonds.
