  • Introduction - BYJUS
    Catenation Carbon has a unique feature of forming long carbon chains i e it attaches with other carbon atoms to form long carbon chains This property is known as catenation This chain can be as big as to contain a total of 70-80 carbon This gives rise to very complex compounds having straight carbon chain, branched carbon chain and ring
  • What are Carbon and its Compounds? - BYJUS
    Catenation Property of Carbon In Organic Chemistry, everything is surrounded by carbon compounds It is one of the most essential components of living organisms There are two stable isotopes of carbon 12C and 13C After these two one more isotope of carbon is present 14C Carbon is used for radiocarbon dating and it is also a radioisotope with a half-life of 5770 years One of the most
  • CBSE Class 10 Science Notes Chapter 4 Carbon and Its Compounds
    Catenation occurs most readily with carbon due to its small size, electronic configuration and unique strength of carbon-carbon bonds Tetravalency, catenation, and the tendency to form multiple bonds with other atoms account for the formation of innumerable carbon compounds
  • What is meant by catenation? Name two elements which show the property . . .
    Part 1: Catenation The property of one element to bond with itself to form long chains or ring-like structures is called catenation The chain can be in the form of open-chain or a cyclic ring Part 2: Elements showing catenation In the periodic table, there are only a few elements that can show this property i e catenation Carbon and Silicon are common examples of element showing catenation
  • Why is catenation property of phosphorus greater than nitrogen?
    Catenation is the bonding of atoms of the same element into series called a chain Thus, higher the stability of single bond between the same atom more will be its affinity to undergo catenation The single N-N bond in nitrogen is weaker than the P-P bond in phosphorus because of high inter-electronic repulsion of the non-bonding electrons, owing to the small bond length As a result, the
  • Lakhmir Singh Solutions for Class 10 Chemistry Chapter 4 Carbon and Its . . .
    Lakhmir Singh Solutions for Class 10 Chemistry Chapter 4 Carbon and Its Compounds are provided here in PDF Carbon is an important entity that occurs in both organic and inorganic forms It is a non-metal having a symbol of ‘C’ and a main constituent of coal The name carbon is derived from the Latin word ‘carbo”, which means coal All living organisms, plants and animals are made up
  • The correct order of catenation is - BYJUS
    The correct option is A C> Si> Ge ≈Sn Correct option is A) C> Si> Ge ≈Sn As covalent bonding takes place in the process of catenation, it is a characteristic of a non-metal Metals have the tendency to form the ionic bonds by losing their electrons while covalent bonds are formed by the non-metals by sharing of electrons All the given elements belong to group 14 of the periodic table We
  • Why does nitrogen show catenation properties less than phosphorus? - BYJUS
    Question Why does nitrogen show catenation properties less than phosphorus? Solution The single N--N bond is weaker than the single P--P bond due to high interelectronic repulsion of the non-bonding electrons in N 2, owing to small bond length Therefore, the catenation property is weaker in nitrogen as compared to phosphorus Suggest
  • What is the Valency of Carbon? - BYJUS
    Catenation Tetravalency Size of a carbon atom Although there is no specific definition, the compounds in solid, liquid or gaseous state which contain covalently bonded carbon atoms in their molecules are known as organic compounds Let us see how the tetravalent nature of carbon affects carbon compounds Recommended Videos
  • The correct order of Catenation property is: - BYJUS
    Higher the bond energy more will be catenation the bond energy order for C−C> S−S>P −P> Si−Si>N −N are 347, 213, 213, 176, 159, 138 kJ mol−1 and hence same is the catenation property order
