The elements placed in group 7 (VIIA) of the periodic table are called halogens or salt producers. All these elements form salts called halides, e.g. NaCl, NaI, KCl, KI etc. Halogen is an ancient Greek word meaning 'salt producer'. Halogens have seven electrons in the..

B 2 H 6 reacts with halogens under different conditions to form halodiboranes. ..

On treating phenol with bromine, different reaction products are formed. When the reaction is carried out in a solvent of low polarity such as CHCl 3 or CS 2 and at low temperature, monobromo phenols are formed. The highly activating effect of -OH group on the benzene ring allows the pola..

There is no direct method for the detection of oxygen in organic compounds. It's presence is detected indirectly. For example, If any organic compound on heating in a dry test tube, gives out water vapor, then the presence of oxygen in the organic compound is indicated. If..
