The number of sigma and pi bonds are,

Sigma Bonds = 16

Pi Bonds = 3

Explanation:
Every first bond formed between two atoms is sigma. Pi bond is formed when already a sigma bond is there. While in case of Alkyne (triple Bond) there is one sigma and one pi bond already present, so the third bond is formed by second side-to-side overlap of orbitals, hence, a second pi bond is formed.
Below all black bonds are sigma bonds, while in alkene there is one pi bond and in alkyne there are two pi bonds.

Sigma and pi bonds are the bonds between atoms that are formed because of the overlapping of the orbitals. There are 16 sigma and 3 pi bonds in Hep- 4- ene- 1-yne.

What are sigma and pi bonds?

Sigma bonds are the strongest covalent bond and are the first bond between the atom that is formed by the overlapping of the bonding axis of the hybrid orbitals.

Pi bonds are the chemical bonds that are formed due to head-on overlapping of the p orbitals of the atoms. They are the third and the second bond of the atoms.

In the case of alkyne in a molecule second and third pi bonds are present and another is formed by the sidewise overlapping of the p orbitals. The third pi bond is present in the alkene molecule.

All the single bonds or the alkane have sigma bonds hence, 16 sigma bonds are present in the structure.

Therefore, there are 16 sigma and 3 pi bonds in Hep- 4- ene- 1-yne.
