Anthracene fullerene is a polycyclic aromatic hydrocarbon. There are three benzene rings consisting of 1 sigma and 2 pi bonds.
There is a sigma and a pi bond in a double bond.Single bond has only a sigma bond.
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)
8 sigma bonds and 1 pi bond.
The aldehyde group -CHO contains 1 sigma bond ( C-H), 1sigma bond (C-O) 1 pi bond (C-O). And there is also another sigma bond attaching it to the rest of the molecule.

Thirteen. There is one sigma bond per double bond (there are 5 double bonds between carbon atoms) and one sigma bond per single bond (there are 8 C-H bonds).
One ionic sigma bond.
Two pi bonds and one sigma bond.
The diatomic chlorine molecule has 1 sigma and 0 pi bonds.
