Chemical Composition of Chloroform
Chloroform is a chemical compound made of carbon, hydrogen, and chlorine. Its molecular formula, CHCl3, shows how these elements are arranged. This arrangement gives chloroform its unique properties.
Molecular Formula and Mass of Chloroform
Chloroform's molecular formula, CHCl3, tells us it has one carbon, one hydrogen, and three chlorine atoms. Its molar mass is 119.38 g/mol. This makes chloroform denser and heavier than many other solvents.
Chemical Bonds and Electron Configuration
The bonds in chloroform are key to understanding its structure and how it acts. The bonds between carbon and hydrogen, and carbon and chlorine, are polar. This polarity makes chloroform a good solvent and helps it form hydrogen bonds with other molecules.
