Product of reaction predicting

There are millions of chemical reactions occurring around us everyday.So many different chemical reactions would be very difficult to understand. However, the millions of chemical reactions that take place each and everyday fall into only a few basic categories. Using these categories can help predict products of reactions that are unfamiliar or new.

Hydrolysis of condensed 1,2,3-triazines results in cleavage of the heterocycUc ring and is in many respects an unexceptional and fully predictable type of reaction. The relative ease with which ring fission takes place, and the products formed, depend almost entirely on the nature of the substituents at the 3- and 4-positions and on the reaction conditions employed. Moreover, hydrolysis under basic conditions normally leads to fission of the N,—C4 bond whereas under acidic conditions most 1,2,3-benzotriazine derivatives behave as masked diazonium compounds, and hydrolysis proceeds with fission of the Nj— N3 bond and transient formation of a diazonium compound, from which the observed products are ultimately derived. Hydrolysis of certain derivatives probably also involves covalent hydration as the key step. 

Often, just looking at the different transition states is sufficient to rationalize the observed product, and ultimately to predict the product of reactions yet to be examined experimentally. Two examples illustrate the point. 

Skill in balancing equations will increase very quickly with practice, especially as you learn to recognize the various types of chemical reactions. Once you have recognized the types of chemical reactions, you will be able to predict the products if you are given just the reactants. A few examples of the more predictable types of reactions are listed below.

When chemical reaction involves more than one apolar solute, short-range hydrophobic association may be important in determining the rate and products of reaction. For example, hydrophobic association between apolar reagent and apolar substrate can enhance the rate of reaction in water (Cayley and Margerum, 1974). Similarly, hydrophobic interactions between enzyme and substrate are important in enzyme catalysed interactions (Jencks, 1969). The role of hydrophobic association in these reactions has been studied using model systems. For example, aminolysis of 8-quinolyl octa-noate by octylamine or decylamine is faster than predicted on the basis of the behaviour of lower amines, the rate enhancement being...
