Diels Alder reactions fall under the pericyclic reaction category, where a cyclic rearrangement of bonding electrons occurs. This means that bond breaking and reforming happen instantly. As there are no intermediates involved, this reaction takes place in one step, making it stereospecific. Hence, substituents cannot undergo any changes. Once the experiment is finished, colorless platelike…

Frequently Asked Questions about Chemical Reaction

Don't hesitate to contact us. We are ready to help you 24/7

How do you describe chemical reactions?
A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What are reaction types?
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.
What is the importance of balancing chemical equation essay?
A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed. Sort of important if you re trying to decide how much fuel for a spaceship going to Mars!
