Each noble gas element, with its saturated shell electronic configuration, marks the completion of the period in which it is placed. They are chemically inert, but can be made to combine by coordination or by excitation of electrons in case of large atoms.
The characteristic properties of transition metals result from the fact that in these metals the differentiation electron enters into penultimate shell d-orbital. Thus the n-1 d configuration of the metal and its ion plays important part in giving the observation set of properties to the metal or its ion. Shapes of these compounds decided by the electronic configuration of metal ion and hence the type of hybridisation which the metal ion undergoes during coordination of the ligands. Tri-idomethane Iodoform is used as an antiseptic and this nature is due to iodine that is liberates.
However because of its very unpleasant smell, it has now been replaced by better antiseptic. It is used in the manufacturing of pharmaceuticals. If this reagent is added to a specimen of alcohol then if white turbidity appears immediately it is tertiary alcohol. This turbidity is due to the formation of alkyl chloride in general. In common system, the cyanides are named as alkyl or aryl cyanide whereas in IUPAC system they are named as alkane or arene nitriles.
Niacin is nicotinic acid and niacin amide nicotinamide. Both contain a pyridine ring system. Niacin is obtain form fish, yeast, beans and peanuts. Milk and fish contain only a low account of this vitamins.
Artificial Sweeteners are the chemical compounds which give sweetening effect to food and enhance its odour and flavour. A very popular sweetening agent is saccharin. The Solid State Point Defects — The defects caused by missing or misplaced atoms or ions in the crystal. Electrochemistry A galvanic cell is represented by writing the anode where oxidation occurs on the left hand side and cathode where reduction occurs on the right hand side.
Chemical Kinetics Chemical Kinetics — The branch of chemistry which deals with the study of reaction rates and their mechanism. Surface Chemistry A colloidal solution in which there is great affinity between the disperse phase and the dispersion medium is called Lyophilic Solutions.
