I would guess that the answer here is endothermic or unfavourable. Endothermic reactions take in energy from the surroundings (in the form of heat). Formation of additional bonds between carbons anyway is generally unfavourable, therefore it needs to take in energy from its surroundings (thus the reaction vessel becomes cold)
This is a chemical reaction.
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
A new molecule is formed after a chemical reaction.
In a chemical reaction sometimes old bonds are broken and new bonds are formed.
In the activated complex of a chemical reaction, bonds are partially broken and formed simultaneously as reactants transition to products. The activated complex represents a transient state where certain bonds in the reactants are weakening, while new bonds in the products are beginning to form. This state is crucial for overcoming the energy barrier of the reaction, enabling the transformation of reactants into products. Ultimately, the activated complex leads to the formation of the final product once the reaction progresses past this critical point.
This is a chemical reaction.
The energy released during a chemical reaction represents the breaking of bonds between atoms or molecules. This energy is the result of the release of the potential energy stored in these bonds.
In a chemical reaction, the bonds of the reactants are broken. The atoms will rearrange and new bonds will form.
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
The atoms involved in a chemical reaction have their bonds broken, new bonds formed, or existing bonds rearranged depending on the reaction type.
The existing chemical bonds break and new bonds are created to give products.
They are called chemical bonds, or just bonds.
Some or all of the existing chemical bonds in the reactants are broken and new chemical bonds are formed in the products.
A new molecule is formed after a chemical reaction.
do not break bonds
