Online Chemistry Courses: Bonding with Science

Chemistry is one of those subjects and disciplines that we rarely think about, even though it’s always around us or even within us. And you probably think it takes years to learn and be proficient in. That's partially true, but with online chemistry courses you’ll be able to develop a solid understanding of the discipline in a relatively short time.

There are various aspects of chemistry and therefore numerous chemistry classes online available. I went through the best online learning platforms and will present you with a selection of both premium and free online chemistry courses in this article.

Why Chemistry?

Firstly, let’s discuss why you could want to take online chemistry courses in the first place. What I like about chemistry is that there are so many opportunities.  For example, with chemistry knowledge, you could go into pharmaceuticals, different manufacturing processes, toxicology, chemical engineering, and various other fields.

Even within a specific field, you could stick with theoretical knowledge and analyze various compounds and reactions. You could also do something more practical and interact with certain substances and see how they work

And with online chemistry courses available, learning is just so simple and so accessible.

Within only several weeks or months, you could end up absorbing the same amount of information or knowledge that would take years to study at a university. Of course, it depends on how much time and effort you invest, but that can be said about absolutely anything.

Types of Chemistry

One of the main reasons why chemistry covers so many fields, is that there are many branches of chemistry. Depending on the source, chemistry can be divided into up to 10 different types.

Most of these subtypes can be grouped into these 5: organic chemistry, inorganic chemistry, analytical chemistry, biochemistry, and physical chemistry. 

Organic chemistry studies organic compounds and their structure, reactions, or other properties. Usually, organic compounds are considered to be the ones which contain carbon. More specifically, carbon bonding with hydrogen.

Organic compounds make up the base of many pharmaceuticals, petroleum products, agricultural chemicals, and similar.

Inorganic chemistry covers… well, inorganic compounds, as you probably have guessed. This chemistry type is basically about chemical compounds that do not contain carbon, although there can be a few more complicated exceptions.

Mostly it’s applied to the chemical industry in areas such as pigments, fuels, coatings, but also some medications and agriculture

As you can probably tell by its name, biochemistry combines two different scientific fields — biology and chemistry. This branch of chemistry studies chemical processes regarding living organisms. Or chemical processes inside the living organisms themselves. 

Biochemistry can be further divided into three types:

  • Structural biology — deals with the structure of molecules
  • Enzymology — studies certain proteins
  • Metabolism — life-sustaining chemical reactions in organisms

Physical chemistry analyzes physics concepts in chemical systems. In other words, it oversees how physical principles influence the way atoms, molecules, or other chemical systems behave.

The main subtopics that physical chemistry studies are:

  • Kinetics — the way reactions happen and their speeds
  • Spectroscopy — the way light interacts with matter
  • Quantum mechanics — arrangement of electrons in atoms and molecules
  • Thermodynamics — how temperature influences energy and work

Analytical chemistry is more related to processing various substances than figuring out how they work. This branch of chemistry uses various instruments and methods to identify and quantify matter

Whichever branch you choose — or maybe several of them — there are plenty of online chemistry courses available for you to indulge in. Let’s dive right into them.
