There are 7 sigma bonds, 3 pi bonds in Cumulene.
Remember there are many forms of cumulene. In a cumulene that forms like this H2C=C=C=C=CH2 there are 7 sigma bonds and 3 pi. When there is a double bond ( = ) one is always a sigma bond the other is pi, single bonds are sigma.
there are 97 sigma bonds and 11 pi bonds
one sigma and one and half pi bonds
13 sigma bonds and 0 pi bonds
There are 5 sigma bonds and 1 pi bond in C2H3Cl.

39 sigma and 6 pi bonds
It has one sigma bond and two pi bonds
sigma bonds=9 and pi bonds=2
there are 97 sigma bonds and 11 pi bonds
Well sigma bonds are a single bond basically, and pi-bonds are double. In a nutshell if you count them there are 16 total bonds. In a pi-bond you have sigma bonds as well so for sigma there are 16. For pi bonds there are 2!
one sigma and one and half pi bonds
Sigma and pi bonds are nucleophiles. Pi bonds are more nucleophilic than sigma. Electrphilic is not a term usually associated with either sigma or pi bonds.
13 sigma bonds and 0 pi bonds
There are 5 sigma bonds and 1 pi bond in C2H3Cl.
8 sigma bonds and 1 pi bond.
Two pi bonds and one sigma bond.
