Why are carbon and its compounds used as fuels for most applications

An organic compound A on heating with concentrated H 2 ​ S O 4 ​ gave product B and on warming with alkaline K M n O 4 ​ gave compound C. Compound A on heating with compound C in presence of concentrated H 2 ​ S O 4 ​ formed compound D, which has a fruity smell. Identify the compounds A, B, C and D.

Two of its well-defined forms, amorphous carbon does. Fullerene was serendipitously discovered in 1985 as a synthetic product in the course of laboratory experiments to simulate the chemistry in the atmosphere of The word carbon probably derives from the Latin carbo, meaning variously “coal,” “charcoal,” “ember.” The term diamond, a corruption of the Greek word adamas, “the invincible,” aptly describes the permanence of this crystallized form of carbon, just as graphite, the name for the other graphein, “to write,” reflects its property of leaving a dark mark when rubbed on a surface. Before the discovery in 1779 that graphite when burned in Get a Britannica Premium subscription and gain access to exclusive content. Pure diamond is the hardest naturally occurring substance known and is a poor conductor of Each of the “amorphous” forms of carbon has its own specific character, and, hence, each has its own particular applications. All are products of Carbon, ...

Answer Carbon and its compounds are used as fuels for most applications because they burn in the air releasing a lot of heat energy[ Therefore, carbon and its compounds are widely used as fuel for most applications due to their high efficiency and heat production[ Websites • • • • • • • • Relevant Images Below are images relevant to your question

Hint: Carbon is a well-known abundant element. It has an atomic number of 6. The electronic configuration of carbon is $\left[ $. Carbon has atomic mass of 12.0107 u. Complete step-by-step solution: Carbon is placed in group 14 of the periodic table. Carbon and its compounds consist of the maximum number of hydrogen and carbon. This makes them have high calorific value. So, most of the compounds of carbon release high amounts of energy. Saturated hydrocarbons burn with a clean flame without any smoke and thus are environment friendly. Because of this, carbon and carbon compounds are used as good fuels. Additional information: Carbon is the most important constituent for the resources of fossil fuels such as petroleum, oil shade, coal gas, coal tar, coal, ethanol, petroleum, ethane, LPG, CNG etc. The two main carbon fuels are fossil fuels and biofuels. Biofuels are extracted from organic matter and are then harvested. Fossil fuels such as coal, natural gas and oil are derived from the ground. Biofuels also take part in the carbon cycle, photosynthesizing carbon dioxide. Burning of both biofuels and fossil fuels produces carbon monoxide. Carbon monoxide is toxic, and it can kill a person on mixing with the haemoglobin in the blood, on increasing the concentration of carbon monoxide, concentration in the body. Biofuels and fossil fuels also produce other air pollutants depending on the fuel. Note: Students may get confused about which are carbon-based fuels. Two most importan...
