Best Answer

catenation ability is highest for carbon atoms, the reason lies in bond energy

bond energy b/w c & c is of same magnitude or sometimes more as compared to bond energy b/w c & other elements,because of this energy carbon is able to form very long chains without breaking

Carbon belongs to fourth group of Periodic Table having valency 4 so it can form covalent bonds with other elements and carbon also easily forming a tetrahedral structure which can extend up. Also it is small in size so bond energy is higher.

whereas bond energy b/w Si & Si is less as compared to bond energy b/w Si & other elements

What is catenation of Pb?

catenation is the property of carbon that it can join with other carbon atoms to form carbon-carbon bonds. this can result in yhe formation of compounds with long change.


What is Phenomenon catenation?

Phenomenon Catenation is a link to self of the atoms of elements to produce lengthy chains Carbon is an example


What is Catenation and hybridization of carbon?

Catenation is a unique property of carbon to link with other carbon atoms to form rings or chains with the help of covalent bonds. Catenation is the reason for the presence of a large number of organic compounds in nature.


WHY Organic compound exist in large number?

It is due to the catenation ability of carbon, carbon atoms may arrange themselves in different ways and carbon-carbon bonding is not easily attacked by other substances.


What is meant by term catenation?

Catenation is the linkage of atoms of the same element into longer chains. Catenation occurs most readily in carbon, which forms covalent bonds with other carbon atoms to form longer chains and structures. several other main group elements exhibit catenation, including silicon and sulfur.


What is the atomicity for carbon?

Atomicity means no: of carbon atoms present in its molecule. carbon has high catenation ability, so any no: of carbon atoms can join together to form a molecule. hence atomicity is also very high. If you mean atomic number, it is 6. If you mean atomic weight, it is 12.0107(8).


Define the term catenation?

carbon atoms have a remarkable property of joining with one another in a large number to form a long chain and rings.this property is known as catenation or self linkage.


What does catenate mean what happens when carbon catenates?

Catenation of carbon means the atoms bonds with like atoms. A good example of this is called hydrocarbon chains which arechainsof carbon attached to one another. There is no limit to the number of carbon atoms that can be formed in a chain. I hope this helps.-M.E.C.A.


What give carbon the ability to form chain that are almost unlimited in length?

A carbon atom can bond to other carbon atoms The reason is because carbon has the ability to form into its self. Carbon has catenation power, which means it can form bonds with other carbon atoms, and this bonding of carbon in a long chain is called carbon chain. The compounds which form by the long carbon chain are known as organic compounds Carbon is in group 14 on the Periodic Table, which means it has 4 electrons in its outer shell. This means carbon has the ability to form up to 4 covalent bonds, sometimes with itself, thus we see 'latice' like structures form (diamond) which have incredible strength. This ability is similar in hydrocarbons and proteins, but not to the same strength which is seen with the 3D lattice affect. Hydrocarbon is a long chain of carbon atoms which have a repeating units.


Why does carbon form the basis for so many different kinds of compounds?

Carbon has an unusual property called catenation: interconnexion of cabon atoms by C-C bonds in a huge variety.


Can carbon rings can bond together in straight chains branched chains or rings?

yes


Why does carbon bond with so many different elements?

Carbon can bond with itself, and many other elements.
