Why does coal usually produce more soot than other fossil fuels when burned?

Answer and explanation;

Coal has aromatic hydrocarbons with high molar mass and has a high ratio of carbon to hydrogen. Burning coal produces more soot than burning other fossil fuels does because of it.

Fossil fuel mixtures of hydrocarbons that formed from the remains of plants or animals. Burning fossil fuels increases the amount of carbon dioxide in the atmosphere. This increase may affect temperatures, amounts of rain and sea levels worldwide. Some sulfur and nitrogen are in fossil fuels, and air contains nitrogen.
