Avogadro is my favorite molecular modeling software. It offers a hassle-free user interface which lets you draw different chemical structures easily. You can also change the color of an atom, order of bonds, etc. Moreover, there are different styles to represent a chemical structure.

You can also animate your designed model in Avogadro. Avogadro is a free molecular modeling software for Windows.

It comes with a simple interface which offers a hassle-free chemical drawing. Some commonly used elements carbon, oxygen, boron, fluorine, phosphorus, etc. Other elements can be selected from the built-in periodic table. Another drop-down menu is provided to select the order of bond as single, double, or triple. If you enable Adjust Hydrogens option, the software automatically adjusts the number of hydrogens in a molecular model. In addition to this, you can replace all the hydrogen atoms in a chemical structure with methyl.

Moreover, you will also find a variety of display modes for a chemical structure: Van der Waals spheres, wireframe, simple wireframe, stick , etc. It also has an option to show or hide dipole moment, force, hydrogen bond , etc.

Avogadro provides two types of views perspective view and orthographic view for every molecular model. You can directly insert the 3D structures of chemical groups, like alcohols, aldehydes, alkanes, alkenes, alkynes, amides, amino acids, carbohydrates, carboxylic acids, ethers, fatty acids, ligands, steroids, thiols, sulfoxides , etc. Avogadro is a great molecular modeling software which comes with a lot of features. It is one of the best free molecular modeling software.

Ascalaph Designer is one more good molecular drawing software in this list. You can create molecular models of different compounds by selecting atoms from the periodic table. The Drawing panel comes with some more options along with the periodic table:. The Drawing Panel also shows the information of each atom in the periodic table by clicking on it.

In this virtual Chemistry lab simulator, you can carry out experiments just like in a real Chemistry laboratory. One of the software lets you form molecular structures of different compounds. It comes with different atoms which you can join to form new compounds.

Chem Lab is one of the best free Chemistry simulation software in this list. It lets you carry out experiments just like you do in a real Chemistry lab. It has a list of experiments, out of which you can select any experiment to perform.

Each experiment is divided into 3 parts: Introduction, Procedure, and Observation. Introduction : This part provides you an overview of the experiment that you are going to perform.

All the reactions that will take place in an experiment are written here. Read the complete introduction to know what is going to happen in an experiment. Procedure : This part guides you in step-by-step methods to perform an experiment. All the equipment, like beaker, funnel, etc. Read the steps one by one and do as directed. Observations : This is the observatory part of an experiment. Observe your experiment and prepare notes in this section.

The best part of the software is that it lets you prepare notes on the basis of experimental observations. Do note that the free version of this software comes with a limited list of experiments. Complete list of experiments is available in its paid version. Salts and Solubility is a free Chemistry lab game for Windows. The whole experiment is carried out in a beaker, initially filled with some water. You can empty it or fill more water into it with the help of taps.

A salt shaker is available in the software; shake it to pour salt into the water. There is a scale on the right side of the beaker, which lets you know how much water is currently filled in the beaker. This free Chemistry simulation game also displays the total number of dissolved ions and bonded ions. Both positively and negatively charged ions are displayed with different colors, so you can identify them easily.
