## Subject - Organic Chemistry

Competing reactions are also called parallel reactions, concurrent reactions or simultaneous reactions.

A competing reaction is the type of a complex chemical reaction in which two or more starting materials compete with other starting materials to give in addition to the main products other, frequently undesired side products.

$A+B→P1+P2-main productsA+C→P3-side product 1A+D→P4-side product 2$

Other competing reactions are the simultaneous attack of a reactant at two or more positions of another starting material and the simultaneous degradation of a starting material to various products.
