In the previous article we learnt how fixed values of hyperfine transition frequency of Cs, speed of light, Planck constant, and Avogadro constant are used to define SI units of time, length, mass and amount of substances ...

The energy of most of the molecular vibrations falls into the infrared region (4000 - 400 cm-1) of the electromagnetic spectrum. Infrared (IR) or vibrational spectroscopy is used by organic chemists to: (i) identify functional ...

Reductive elimination (R.E.) is the opposite or the reverse of oxidative addition (O.A.), in which X-Y oxidatively adds on to Ln Mn+ to give Ln (X)(Y)M(n+2)+. LnM Y (n+2)+ X R.E. O.A. LnM n+ + X Y X and Y ...

A good knowledge in coordination and organometallic chemistry is very useful to a student, who wish to understand chemical transformations taking place around in nature and industry. It also helps to design synthetic ...

Isomers (compounds with the same chemical formula) can be broadly classified into (i) stereoisomers (e.g. geometrical and optical) with the same connectivity but having different spatial arrangements and (ii) structural ...

Let me at the outset, share my thoughts with you regarding basic mathematics and its teaching. It is based on my teaching experience over the past couple of decades and based on what I learned for my O/L

Arenes are aromatic compounds which can act These complexes with three simple ligands are called as π-electron donors. Organometallic complexes with such ligands are commonly known as arene complexes, arene metal complexes ...

Mass spectrometry is an analytical technique used to obtain information on the structure and molecular weight/accurate mass of a given compound. The main components of the mass spectrometer are the ion source, mass ...

We know that main group hydrides such as LiAlH4 and NaBH4 are the common reducing agents used by organic chemists to reduce aldehydes, ketones and carboxylic acids. Transition metal hydrides act as ...
