Inorganic Chemistry

Organic chemistry is defined as the chemistry of hydrocarbon compounds and their derivatives then inorganic chemistry can be described generally as the chemistry of "every-thing else." This includes all the remaining elements in the periodic table, as well as carbon, which performs a principal role in many inorganic compounds. Organometallic chemistry, a very large and rapidly developing field, bridges these two areas via thinking about compounds containing direct metal-carbon bonds, and consists of catalysis of many organic reactions.
