Drugs are broadly classified into following types depending on the purpose for which they are used. 1. Antipyretics
Briefly state the pH of an Alkyl Halide?
The absorption of microwave radiation increases the rotational energy of molecules and gives information about the moment of inertia of the molecules.Now we can begin the study of the spectroscopy that explores the different ways in which the energy of the
