Chemical Reactions -A chemical reaction is in which the bonds are broken within reactant molecules, and new bonds are formed within product molecules in order to form a new substance. Chemical reactions are all around us. Chemical reactions are continually taking place on our planet. To learn Definition, Equations, Types, Examples with FAQs of Chemical Reactions.

The rate of reaction refers to the speed at which the products are formed from the reactants in a chemical reaction. It gives some insight into the time frame under which a reaction can be completed. For example, the reaction rate of the combustion of cellulose in fire is very high and the reaction is completed in less than a second.
Disproportionation reaction, also called dismutation reaction, is basically a type of redox reaction involving simultaneous reduction and oxidation of atoms of the same element from one oxidation state (OS) to two different oxidation states. Basically, one compound of intermediate oxidation state gets converted to two compounds, one with higher and the other with lower oxidation states.
A neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H + ions and OH – ions which form water. A neutralisation reaction is generally an acid-base neutralization reaction. Table of ...
Oxidation and Reduction reactions- The chemical reactions which involve the transfer of electrons from one chemical substance to another. These electron-transfer reactions are termed as oxidation-reduction reactions or Redox reactions. The oxidation and reduction reaction also involve the addition of oxygen or hydrogen to different substances. To learn more about the examples of oxidation and reduction reactions, Writing Balance Chemical reaction. Visit BYJU’S for detailed information.
A reaction related to the Wurtz Reaction in which aryl halides are used instead of alkyl halides is often called the Wurtz-Fittig reaction and is a very important named reaction in organic chemistry. Wurtz Reaction Equation. The general form of the Wurtz reaction equation can be written as follows: 2R-X + 2Na → R-R + 2Na + X –
A double decomposition reaction is a type of decomposition reaction in which two constituent reactants interchange positive and negative ions and form two new compounds. Example. HCl(aq) + NaOH(aq) → NaCl(aq) + HOH(l) Types of Decomposition Reaction. The three primary types of decomposition reactions are: Thermal decomposition reaction
It is a one-step reaction and the reaction speed is driven by the steric effects. During the intermediate step, the position of the leaving group is inverted whereas the nucleophile is 180°. Nucleophilicity also affects the reaction rate. Learn more about the S N 2 reaction mechanism in detail. S N 1 Reaction – Mechanism of S N 1 Reaction
Single Displacement Reaction. A single displacement reaction which is also called as single replacement reaction is a kind of oxidation-reduction chemical reaction when an ion or element moves out of a compound, i.e., one element is replaced by the other in a compound.
Precipitation Reaction – Definition and Meaning. The term ‘precipitation reaction’ can be defined as “ a chemical reaction occurring in an aqueous solution where two ionic bonds combine, resulting in the formation of an insoluble salt”. These insoluble salts formed in precipitation reactions are called precipitates. Precipitation ...
