ACD/ChemSketch allows for both basic structure drawing and importation of 3D and 2D .MDL files from other molecular modelling programs. ChemSketch has been favorably compared to other molecular modelling software, especially ChemDraw, based on its ability to display a wide range of structural components and the ease of creating complex structures quickly.
ChemDraw is a molecule editor first developed in 1985 by Selena "Sally" Evans, her husband David A. Evans, and Stewart Rubenstein [1] [2] (later by the cheminformatics company CambridgeSoft).
It gathers users' notes, drawings, screen clippings, and audio commentaries. Notes can be shared with other OneNote users over the Internet or a network.

Computational chemistry can help predict values like activation energy from catalysis. The presence of the catalyst opens a different reaction pathway (shown in red) with lower activation energy. The final result and the overall thermodynamics are the same. Computational chemistry is a tool for analyzing catalytic systems without doing experiments.
Propylene carbonate (often abbreviated PC) is an organic compound with the formula C 4 H 6 O 3. It is a cyclic carbonate ester derived from propylene glycol. [4] This colorless and odorless liquid is useful as a polar, aprotic solvent. [5] Propylene carbonate is chiral, but is used as the racemic mixture in most contexts.
