Question
Study the following flow chart and identify the substance ‘X’ and ‘Y’ formed in the below reaction.
- X = Charcoal and Y = coke
- X = Coke and Y = coal tar
- X = Coke and Y = coal tar
- X = Soft coke and Y = hard coke
Hint:
Destructive distillation is a chemical process that decomposes raw materials by heating them to high temperatures. The term generally refers to the treatment of organic materials in the absence of air or in the presence of limited amounts of oxygen or other reagents, catalysts, or solvents.
The correct answer is: X = Coke and Y = coal tar
The correct option is b)X = Coke and Y = coal tar.
When coal undergoes destructive distillation, it produces coke, coal tar , coal gas and ammonia solution.
When coal tar under goes fractional distillation is then forms benzene.
The same way coke forms iron oxide.
