Case Study Question 02

Science

Chapter 4: Carbon and its Compounds

Class 10

Read the following passage carefully and answer the following questions:
As a versatile element, carbon can form large compounds because of its tetravalency and the property of catenation that it exhibits. Here, catenation refers to the combination of carbon atoms with itself to form large molecules. Carbon forms stronger covalentbonds with itself and other elements such as hydrogen, oxygen, sulphur, nitrogen and chlorine. This is because its nucleus has a strong force of attraction and holds these bonds tightly together.
