A chemical reaction in which bonds are created is usually associated with ________.
Nikolay [14]

A  reaction in which bonds are created is usually associated with the Release of energy.

What are the various types of bonds?

There are three sorts of bonds:

1. Electrovalent or  electrovalent bond

2.  chemical bond

3.  dative bond

Electrovalent or electrovalent bond are formed when one or more electrons are transferred from one atom to another.

Covalent bonds are formed when the atoms during a  molecule share an equal number of electrons.

A dative bond is one in which both electrons in a shared pair come from the same atom.

Now, atoms tend to stabilize once they form chemical bonds, releasing energy within the process. Energy is released because there's a higher level of stability associated with a low energy level.

Hence, a  reaction in which bonds are created is usually associated with the release of energy.
