b) Catenation- Catenation is the binding of an element to itself through covalent bonds to form chain or ring molecules.

Answer 2

Answer:

1=Unsaturated hydrocarbons: Hydrocarbons in which the carbon atoms are linked to each other by double (C=C) or triple (C≡C) bonds are known as unsaturated hydrocarbons. Examples include ethene (H2C=CH2), propyne (HC≡CH−CH3 etc

2= Catenation is the linkage of atoms of the same element into longer chains.
