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 7 sigma bonds, 3 pi bonds in Cumulene.
we have 15 sigma (8 C-C & 7 C-H) and 3 pi bonds.
6 sigma bonds, 2 pi bonds.

7,3
There are 7 sigma bonds, 3 pi bonds in Cumulene.
There are five covalent bonds present in an ethyne molecule.
there is one
Each molecule of carbon dioxide has two C=O double bonds, like this: O=C=O.
There are two double bonds in a carbon dioxide molecule.
There are 7 sigma bonds, 3 pi bonds in Cumulene.
There are five covalent bonds present in an ethyne molecule.
there is one
none. its a triple bond. N≡N
Each molecule of carbon dioxide has two C=O double bonds, like this: O=C=O.
It gives a very strong indication of the degree of unsaturation of a molecule and hence how many double bonds are present.
