How to name an alkyne compound according to IUPAC!

identify the functional group of each compound.

Polyisobutylene, a synthetic high molecular weight alkane with many properties similar to polyethylene (Section 11.5A), is the principal component of Elastol, a product used to clean up oil spills. Elastol dissolves oil to form a thick mat that can be skimmed or suctioned from the surface. Explain why oil dissolves in Elastol.
