Alpha Pi Sigma has many calls.
Phenol has 6 sigma bonds and 1 pi bond.
A pi bond is weaker than a sigma bond because pi bonds have less overlap between the orbitals of the bonding atoms compared to sigma bonds. This results in pi bonds being easier to break in chemical reactions.
There is a double bond between the two carbons, so that is one sigma bond and one pi bond. The hydrogen's all are sigma bonded to the carbons so there are four sigma bonds there. So, there is one pi bond overall and five sigma bonds overall.
2 sigma bonds & 0 pie bonds (I think not conformed)
In a chlorine molecule (Cl2), there is one sigma bond and one pi bond. The sigma bond is formed by the head-on overlap of atomic orbitals, while the pi bond is formed by the sideways overlap of p orbitals.
