Carbon monoxide is a good π-acceptor and the M-C bond in metal carbonyls [M(CO)n ] has a significant π character. Thus, the M-C bond is strengthened and the carbon oxygen bond is weakened with the increase in back bonding.

Metathesis of simple salts is a double replacement reaction as shown below. AX + BY → AY + BX In Greek, “Metathesis” is known as the change of position or transposition. Olefin metathesis (OM) is the catalytic scission ...

Let’s begin with something everyone knows, SI units! Everyone of us applies them, but do you know the concept behind its definitions? Very recently definitions of SI units were changed and they are now defined by ...

Organic chemistry is basically the study of synthesis, reactions, properties, and structures of carbon-containing compounds. Organic reactions can be classified into four main types: addition, elimination (E), substitution, ...

Coordinatively unsaturated metal centres (Mn+) (valence electron count, VEC<18) may undergo oxidative addition reactions to form saturated metal complexes by cleaving the X-Y bond of a molecule (e.g. H2 , O2 , ...

A coordination complex of the type [MLx ]n+ is formed when each neutral ligand (L) donates a lone pair of electrons to a metal centre (Mn+). Here, x is the coordination number and n+ is the oxidation number of M. We ...

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 ...

Chromatographic methods are recognized as the most powerful analytical separation techniques to date, for the identification and separation of complex mixtures of chemical compounds.

Molecules have different energy states: electronic, vibrational, rotational, and nuclear. Quantized energy is responsible for each transition (e.g., rotational - microwaves, infrared - vibrational) within the ...
