WebA strong base will have such a great thermodynamic instability (great energy--such as H − or hydride) that it will attack a protic hydrogen to form H 2. A good nucleophile, then, is not as basic and is more likely to be sterically unhindered. Consider CN. It will tend to act as a nucleophile and attack an electrophile. Webacid–base reaction, a type of chemical process typified by the exchange of one or more hydrogen ions, H+, between species that may be neutral (molecules, such as water, H2O; or acetic acid, CH3CO2H) or electrically charged (ions, such as ammonium, NH4+; hydroxide, OH−; or carbonate, CO32−).
