X-Rays - In 1895, Wilhelm Conrad Roentgen, a German physicist observed, while doing some experiments with the discharge tube, that when cathode rays are allowed to fall on a metal target called anticathode placed in their path, a new kind of rays are produced. These radiations are called ..

This has created a revolutionary change in medical sciences. It can take pictures of fractures in bones and diagnose problems such as lung infection et..

In a crystalline solid, the constituent particles (atoms, ions or molecules) are arranged in a regular order. An interaction of a particular crystalline solid with X-rays helps in investigating its actual structure. Crystals are found to act as diffraction gratings for X-rays an..

The general formula of Haloalkane (CnH 2 n + 1 - X) or Haloarene is 'RX' where R - is an alkyl or aryl group and X is a halogen atom (F, Cl, Br or I). The halogen derived hydrocarbons are a highly reactive class of compounds. The reactivity is due to the presence of po..

The general formula of Haloalkane (CnH 2 n + 1 - X) or Haloarene is 'RX' where R - is an alkyl or aryl group and X is a halogen atom (F, Cl, Br or I). The halogen derived hydrocarbons are a highly reactive class of compounds. The reactivity is due to the presence of polar carbon..

The halogen atom in haloalkane is very reactive and can be easily replaced by nucleophiles whereas the halogen atom in haloarenes is strongly held to the nucleus and cannot be replaced easily with nucleophile..
