What is the versatile Nature of carbon? Explain.

Solution

Carbon is a versatile element and is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.

tetra-valency and catenation. It is because of these properties that the element has the capacity to form a large number of compounds.(versatality)

tetra valency

Carbon has the atomic number of 6, meaning each carbon atom has a total of six electrons. Two are in the completed inner orbit, while four electrons are found in the atom’s outermost orbit. This basically means that carbon has four valence electrons (outer electrons that are available for forming bonds with other atoms). Because of this arrangement within the atom’s orbits, carbon is called tetravalent.

The carbon’s four valence electrons can be shared by other atoms (that have electrons to share), thus forming what we call covalent bonds (shared electrons bonds). The carbon atom also has the ability to form a bond with other carbon atoms to create covalent bonds forming long strings of carbon atoms, bonded to each other like links in a chain.

Silicon (Si), another element in group 14 of the periodic table, also has four valence electrons and can make large molecules called silicones. But due to its higher atomic number (in comparison to Carbon), its atoms are too large to fit together into as great a variety of molecules as carbon atoms can.

What makes carbon unique is its ability in forming covalent bonds which are very strong in nature. The small size of the carbon atom makes the compounds of Carbon exceptionally stable. Hence carbon as an element has the ability to form a variety of stable compounds, which can exist freely in nature.

catenation

Catenation

The linkage of atoms of the same elements to form longer chain is called CATENATION.

Carbon due to its tetravalent nature has the unique property to form bonds with other atoms of carbon forming a long chain. Because of its property of catenation, carbon can form a

  • Straight chain
  • Branched chain
  • Cyclic ring

The astounding compound-forming ability of the element comes from the capacity of its atoms bind to each other not only in straight chains but in complex branchings, like the branches of a tree. They can join in a “head-to-tail” structures to make rings of carbon atoms. The element has practically no limit to the number or complexity of the branches or the number of rings that can be attached to them, thus making it unique as there is no limit to the number of different molecules that can be formed.

Carbon atoms have the ability to share not only a single electron with another atom forming a single bond, but it can also share two or three electrons, forming a double or triple bond.This characteristic of carbon allows it to form a high number of possible bond combinations at different places, making a huge number of different possible molecules. What is important to remember is that a molecule that differs from even a single atom or bond position, becomes a molecule of a different compound with different physical and chemical properties.
