what is a pi bond?
2 answers
A pi bond is the sideways overlap of two p orbitals. The sigma bond is a head to head overlap of and s and p or two p orbitals
When the electron orbitals overlap laterally, the bond is called the pi () bond. In pi bonds the resulting overlap is not maximum and these bonds are relatively weak. A molecule of ethylene or ethene (C2H4) has 4 bonds and 2 bonds. In pi bonds the resulting overlap is not maximum and these bonds are relatively weak.
