What is Catenation explain with reference to group 14?
The property of self-linking of atoms of an element through covalent bonds to form straight or branched chains and rings of different sizes is called catenation. Amongst the group 14 elements, C-C bond strength (355 kJ mol1) is maximum, therefore, carbon shows maximum tendency for catenation.
What is Catenation give example?
Updated July 03, 2019. Catenation Definition: Catenation is the binding of an element to itself through covalent bonds to form chain or ring molecules. Examples: Carbon is the most common element that exhibits catenation.
What is Tetravalency class 10th?
Carbon has a valency of four, so it is capable of bonding with four other atoms of carbon or atoms of some other monovalent element. This is known as tetravalency of carbon.
Is Catenation a Tetravalency?
Answer. Catenation is the self-linking property of carbon i.e carbon atoms form bonds with another carbon atom while tetravalency is the property of carbon atom to combine with another atom of another element i.e carbon atoms form bonds with atoms of other elements.
What is Catenation class 10th?
Catenation can be defined as the self-linking of atoms of an element to form chains and rings.
What are allotropes class 10th?
Allotrope: An element, in different forms, having different physical properties but similar chemical properties is known as allotropes of that element. Carbon has three well known allotropes which are graphite, daimond and buck minster fullerene. These are formed by carbon atoms.
What are allotropes short?
Answer: The term allotrope refers to one or more physical forms of a chemical element that occurs in the same physical state. Allotropes may show differences in chemical and physical properties. Swedish chemist Jons Jakob Berzelius proposed the concept of allotropy in 1841.
Which type of carbon is the hardest?
diamond
What allotrope means?
Allotropy, the existence of a chemical element in two or more forms, which may differ in the arrangement of atoms in crystalline solids or in the occurrence of molecules that contain different numbers of atoms.
What is allotrope explain with example?
The term allotrope refers to one or more forms of a chemical element that occur in the same physical state. For example, graphite and diamond are both allotropes of carbon that occur in the solid state. Graphite is soft, while diamond is extremely hard.
What are the two allotropes of oxygen?
There are two main allotropes of oxygen: A diatomic molecule made up of 2 oxygen atoms with the moelcular formula O2 commonly referred to as molecular oxygen or dioxygen. A triatomic molecule made up of 3 atoms of oxygen with the molecular formula O3 referred to as ozone.
How allotropes are formed?
Allotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviours. The change between allotropic forms is triggered by the same forces that affect other structures, i.e., pressure, light, and temperature.
What element has most allotropes?
Carbon
