The basic chemistry of acids and bases. A lot of chemistry requires you to understand the difference between acids and bases. An acid is a substance that donates an H + ion to another chemical species called a base. A base is a substance that accepts (combines with) an H + ion.. If you need to know the concentration of the H + ion in solution, you can do so by representing the H + molarity, [H +].

The elimination reaction. Second-order elimination is called the E2 reaction. Like the S N 2 mechanism, the E2 mechanism takes place in a single step, as shown in the next figure. A base plucks off a proton on a carbon adjacent to the leaving group, forming the double bond and giving the leaving group the boot.
