How can I draw sigma bonds?

1 Answer

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.

In a Lewis structure, a bond is often represented by a straight line:
