Solution:
- Catenation is the binding of an element to itself through covalent bonds to form chain or ring molecules.
- Carbon is the most common element that exhibits catenation.
- It can form long hydrocarbon chains and rings like benzene.
- Please note that the smaller the atom, the stronger is the tendency of catenation.
- All the elements of the carbon family or group 4 family exhibit catenation property.
- The carbon family includes carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).
- The ability of an element to catenate is primarily based on the bond energy of the element to itself, which decreases with more diffuse orbitals.
- The bond length decreases across a row in the periodic table and increases down a group.
- The bond energy of S-S is 266 Kj/mol.
- The bond energy of Si-Si is 340 Kj/mol.
- The bond energy of P-P is 54 Kj/mol.
- The bond energy of N-N is 160 Kj/mol.
