Course Synopsis

The lanthanides include elements from atomic no 58 to 71 and fill their 4f level gradually. Actinides are typical metals and include elements from 89 to 103. These are radioactive elements. The non aqueous solvents comprise an important group of solvents that are used for the reactions which need to avoid water. Although these are quite helpful for performing few reactions but at the same time also possess limitations due to their physical and chemical properties.
