Study Notes

Chemical Bonds and Reactions

During a chemical reaction, chemical bonds are broken and formed.
The type of bond formed in a Lewis acid-base reaction is a covalent bond.

Energy and Bond Formation

When the energy required to break bonds is larger than the energy evolved in making new bonds, the net result is an endothermic reaction.

Lewis Bases

An example of a Lewis base is ammonia (NH3).

Classification of Chemical Reactions

Chemists classify chemical reactions into different categories, including synthesis, decomposition, single displacement, and acid-base reactions.
