Question

Higher percentage of carbon is found in:
A.) Anthracite
B.) Lignite
C.) Bituminous
D.) Peat

Answer 1

Hint: To solve this question we need to know that there are different types of coals and among them anthracite has the highest content of carbon in it . Anthracite has about \[90\% \] of carbon content in it.

Complete step by step answer:
In this question first we will discuss the different types of coals and then the content of carbon in them. There are following types of coal:
$1.)$ Lignite: Lignite is also known as brown coal because of its brown color. It has the least concentration of carbon in it. It has about $20 - 30\% $ of carbon content in it.
$2.)$Bituminous: Bituminous has the highest carbon concentration of about $60 - 80\% $. It is black in color and usually has high heating content and it appears shiny.
$3.)$ Sub-bituminous: Subbituminous has concentration of carbon less than bituminous. It is black in color but not shiny.
$4.)$Anthracite: Anthracite has the highest carbon content of about $85 - 98\% $ of carbon. Due to this it has low ash and smoke formations. It is the best coal that can be used in metallurgical processes.
$5.)$ Peat: Peat is actually not coal, but rather the precursor to coal. It is soft and consists of partially decayed plants. When it is placed under high pressure and heat , then it becomes coal.
Thus, we can conclude from the above theory that anthracite has the highest content of carbon in it.
So the correct option is (A).

Note:
In this question, we need to remember that peat is not really coal but when it is placed under high pressure and heat then it becomes coal with the carbon content of about $20 - 25\% $ in it.
