Hydrocarbons are compunds formed by combination of Hydrogen and Carbon.
Hydrocarbons can be of two type....1. Aliphatic and 2. Aromatic
Aliphatic hydrocarbons can be divide further in two ways...1.From their structure and 2. From their chemical composition
1. Division by structure....There are just two types...1. Straight chain and 2. Branched chain. I won't bore you here but it's as simple as say 4 rods joined in a straight line or three in a straight line and one perpendicular in between...that's division by shape.
By chemical composition it can be divided into 3 types...1.Alkanes 2.Alkenes and 3.alkynes
In alkanes the interlinking Carbon atoms are joined together in a single bond(has a general formula of CnH2n+2)
In alkenes the interlinking Carbon atoms have atleast one double bond among the carbons.(gen formula....CnH2n)
In alkynes the interlinking Carbon atoms have atleast one triple bond among the carbons(gen formula...CnH2n-2)
Aromatic hydrocarbons have a ring structure and have double bonds that keep on shifting position among themselves.
Aromatic hydrocarbons....because of this property are highly stable.

There is a large class of important chemical compounds whose molecules are made up entirely of carbon and hydrogen atoms. These compounds, as a group, are called "hydrocarbons".
Hydrocarbons are the critical energy storage molecules within all major types of fossil fuels (including coal, oil, and natural gas) and biofuels. They also form the feedstock for the production processes of many types of plastics.
Burning hydrocarbons in the presence of oxygen (O2) produces carbon dioxide (CO2) and water (H2O). If there is too much carbon or too little oxygen present when hydrocarbons are burned, carbon monoxide (CO) may also be emitted. Sometimes unburned hydrocarbons are released into the air during incomplete combustion.
Burning fossil fuels, including gasoline in automobile engines, releases some hydrocarbons into the air. In a typical urban environment, the atmospheric concentration of hydrocarbons is around 3 ppm (parts per million). Some hydrocarbons, along with other types of Volatile Organic Compounds (VOCs), contribute to the formation of photochemical smog.
The carbon atoms in hydrocarbons often form long chains or ring structures. Some of the hydrocarbons that you may have heard of include methane (CH4), butane (C4H10), propane (C3H8), benzene (C6H6), ethane (C2H6), and hexane (C6H14).

There are aromatic hydrocarbons and aliphatic hydrocarbons.
The aromatic hydrocarbons all have the benzene ring as their base structure. Most of them also smell good hence the name "aromatic" from their aroma.
Aliphatic hydrocarbons are those which are mainly made of carbon chains. Either straight chains or branched chains.
You could also check up any texts on organic chemistry for more insight. Good luck!!

There are three main types
Alkanes - the most simple - known as saturated hydrocarbons as all atoms fulfill their bonding
Alkenes - unsaturated as there will be a double bond between two of the C atoms
Aromatics which are cyclic.
Look up these in a text book for more information - you have to learn to research things yourself!

hydrocarbons are just molecules with C and H in them. Go open an organic text book and read about alkanes

hmm....
let me tell you something...
when it comes to organic chemistry, you got to learn from the very beginning to understand the later chapter.
If I want to explain to you it will take like many pages, Then i better write a book on that question.
