properties of organic materials

Classification of Magnetic Materials - On the basis of their magnetic properties different materials are classified as: Diamagnetic substance Paramagnetic substance Ferromagnetic substan..

Matter and Materials - Matter exists in several phases. If we look at all objects around us, we perceive that some materials have a definite shape and occupy a definite amount of space or volume. We call these materials solids and we can name many objects that are soli..

(e.g., TiO 2 , NaCl, C 6 H 6 ) are weakly repelled by external magnetic fields. This property is shown only by those substances which contain fully-filled orbitals i.e., no unpaired electrons is presen..

An organic compound with two amino (-NH 2 ) groups. An organic compound with two carboxylic (-COOH) groups. For example: Adipic acid [HOOC(CH 2 ) 4 .COOH] Hexamethylene diamine [H 2 N(CH 2 ) 6 .NH 2 ] The Nylon formed in this case is otherwise known as nylon-66 because each of ..

Introduction - The simplest organic compounds are hydrocarbons. All organic compounds can be derived from hydrocarbons by substituting a hydrogen atom with a suitable functional group. Replacing a hydrogen atom by a OH group in a hydrocarbon, gives an alcohol: replacement of H a..

Organism and Environment - Each and every living organism has its specific surrounding medium of environment with which it continuously interacts and remains fully adapted. The environment is the sum total of physical and biotic conditions influencing the responses of the o..

It reduces many organic compounds. For example, compounds containing carbonyl group (-CO) are reduced to alcohol..

Neoprene is superior to natural rubber because of the following properties: Neoprene is non-inflammable but natural rubber is inflammable Neoprene is resistant to oils, organic solvents, petrol and grease. Natural rubber swells and rots in contact with these materials..

The properties of temperature, pressure, humidity rainfall, sunshine cloud and wind in a given place and time is called weather. The average weather conditions of an area, which includes atmospheric conditions, seasons. etc. constitutes the climat..

Introduction - Organic chemistry is that branch of chemistry which deals with the study of compounds of carbon with hydrogen (hydrocarbons), and their derivatives. Presently about five million organic compounds are known. Since the synthesis of urea from ammonium thiocyanate, ma..
