Ionic Bond Formation, Types & Examples | What is an Ionic Bond? Faced with a wide range of varied interactions between chemical substances, scientists have likewise found it convenient (or even necessary) to classify chemical interactions by identifying common patterns of reactivity. If a chemical synthesis starts from basic laboratory compounds and yields something new, it is a "purely synthetic process". Why do you think the steel wool changed color after it was heated? In this approach, the molecule is broken up into two or more parts called synthons. Double displacement - A double displacement reaction is also called a metathesis reaction. They are denoted by a double arrow pointing both directions. Consider, for example, a reaction similar to the one yielding \(\ce{NaCl}\): The product of this reaction is a covalent compound, so transfer of electrons in the explicit sense is not involved. In the reaction between sodium and chlorine to yield sodium chloride, sodium is oxidized (its oxidation number increases from 0 in Na to +1 in NaCl) and chlorine is reduced (its oxidation number decreases from 0 in Cl2 to 1 in NaCl). However, most of the reactions can also be written down with the help of special equations. In other words, these reactions can take place in either direction according to the conditions that are present. Chemical reactions differ not only by the type of reactants but also by the time it takes to get the final product. Synthesis reactions, which involve single displacement, double displacement, and combustion reactions, are one of the most common types of chemical reactions. Using this oxidation number and the compounds formula, guideline 4 may then be used to calculate the oxidation number for sulfur: \(\ce{charge\: on\: H2S}=0=(2\times +1)+(1\times x)\).
