i cant understand anything in carbon and its compounds. can you give me any the basics of what i need to learn in carbon and its compounds

Carbon has a usual oxidation state(valence) of +4 and it can bond to itself. Therefore, there are millions of carbon containing compounds. You must know that thousands of books have been written about the chemistry of carbon so a few lines I write will not tell you that much. Here is a site that you can read that will tell you a little more. http://www.edinformatics.com/math_science/carbon.htm
