Question

2) Define Catenation & Allotropy​

Answer 1

Answer:

Catenation is the ability of carbon to form bonds with other carbon atoms forming long chains...

Answer 2

CATENATION.

Catenation can be defined as the self-linking of atoms of an element to form chains and rings. This definition can be extended to include the formation of layers like two-dimensional catenation and space lattices like three-dimensional catenation.

Catenation occurs most readily in carbon, forming covalent bonds to form longer chains and structures with other carbon atoms. This is why the vast number of organic compounds are found in nature. Carbon is best known for its catenation properties, with the analysis of catenated carbon structures in organic chemistry.

Carbon is by no means the only element capable of forming such catenae, however, and several other main group elements are capable of forming a wide range of catenae, including silicon, sulfur, and boron

ALLOTROPY

Allotropy is the property of some chemical elements to exists in two or more different forms in the same physical state ,known as allotropes of these elements.
