The basic knowledge of chemistry is essential for all; you need to understand certain chemical reactions. A number of changes that you observe are the result of chemical reactions like the rain, the change in the color of leaves, cleaning of any particular material in your house, all involve chemicals. For example, in the of hydrogen bromide, an electrophile proton attacks the double bond forming a , which then reacts with the nucleophile bromine. In the E1 mechanism, the leaving group is ejected first, forming a carbocation. Chemistry is important because everything you do is chemistry! It is essential to make the reaction as efficient as possible, maximizing the yield and minimizing the amount of reagents, energy inputs and waste.

Chemistry in your body 26- Digestion of food : Digestion is based on chemical reactions between food and acids and enzymes to break down molecules into nutrients that the body can absorb and use. Equilibrium Main article: Although the concept of is widely used across sciences, in the context of chemistry, it arises whenever a number of different states of the chemical composition are possible, as for example, in a mixture of several chemical compounds that can react with one another, or when a substance can be present in more than one kind of phase. The theory of a substance at the root of all combustion was propounded by the German in the early 18th century and was only overturned by the end of the century by the French chemist , the chemical analogue of Newton in physics; who did more than any other to establish the new science on proper theoretical footing, by elucidating the principle of and developing a new system of chemical nomenclature used to this day. Therefore, heterogeneous catalysts are preferred in many industrial processes.
