What is Tetravalency class 10th?

Valency of carbon is 4. The outer electronic configuration of carbon is 2s22p2. … It shares these 4 valence electrons to form 4 covalent bonds. Hence, valency of carbon is 4.

This theory was disproved when Friedrich Wohler made urea (an organic compound) from ammonia (an inorganic compound).

Q. Who gave vital force theory?

Berzelius

Q. What do you mean by homologous series?

A homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. We will look at three hydrocarbon series: alkanes, alkenes and the cycloalkanes. Hydrocarbons are compounds that contain only hydrogen and carbon.

Q. Why the Valency of carbon is 4?

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./span>

Q. What is Catenation and Tetravalency?

(a) Catenation: Carbon has the unique ability to form bonds with other atoms of carbon, giving rise to large molecules. This property is called catenation. (b) Tetravalency: 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./span>

Q. What is Catenation Tetravalency of carbon?

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./span>

Q. What is the importance of Tetravalency?

This is called tetravalency of carbon. It is a unique property of carbon as it forms very strong covalent bonds which makes carbon compounds exceptionally stable in nature. The ability of carbon to form covalent bonds with other carbon atoms is called catenation.

Q. What do you mean by Catenation and isomerism?

In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. … In chemistry, isomers are ions or molecules with identical formulas but distinct structures. Isomers do not necessarily share similar properties./span>

Q. Why is Catenation possible in carbon?

The sigma bonds formed by the adjacent atoms in carbon is strong enough so that perfectly stabilized chains can be formed between the atoms. This is the reason why carbon exhibits the catenation property.

Q. Why is carbon called tetravalent?

The carbon atom has four electrons in its outermost shell. … Thus, we can say that carbon is tetravalent. The word tetravalent means having a valence of four because of the prefix – tetra. Carbon is considered tetravalent because it has four electrons in its outermost orbital.

Q. What is the definition of allotropes?

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./span>
