Question

Write two important uses of coke.

Answer 1

Hint: In chemistry, carbon is a very versatile element which has a tetravalent structure which means it can attach to mostly four elements at a time, but it also shows a wide variety of bond structure ranging from the single bond, double bond and triple bond. All these bonds take different types of strengths and exist with different electrons which are in participation.

Complete step by step answer:
Carbon is a very versatile element and showcases a wide range of bond types ranging from single to triple. All these bonds exist but the properties of these bonds are very different. The carbon is said to be most stable in its quaternary state which means the carbon is the most stable when it is surrounded by four other elements. This is possible only when all the elements are connected to the central atom through the single bond.
The coal which is a well-known carbon compound can be converted to yet another carbon compound coke for the commercial use and utilization.
The coke can be used for the heating purposes for the ovens and heaters. In some cases, it is more preferred than coal as its combustion is free of smoke. It is also used for the creation of iron in the impact heater and is also used for the production of steel and different materials.

Note: Carbon is a tetravalent atom which means it has four valence electrons and thus can form four covalent bonds with atoms.
Based on this property the carbon atom can be categorised as primary, secondary or tertiary
The carbon which is attached to only one other carbon atom is called primary carbon, the carbon atom with the attachment of two other carbon atoms is secondary carbon whereas the carbon atom with the attachment of three carbon atoms is termed as a tertiary carbon atom.
