the halogens exist at room temperature in all three states of matter:

In halogenations, the nature of the products depends upon the reaction conditions. Benzene in the presence of a halogen carrier e.g., FeCl 3 or iodine, reacts with chlorine and bromine even in dark and at room temperature to give mono- and di-hal..

States of Matter - Normally matter exists in three forms: Solid Liquid Gases Heat energy can bring about a change of state in matter from solid to liquid and liquid to gaseous state. Suppose a solid is heated continuously at cons..

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. ..

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 allow..

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..

Effect of Temperature and Pressure on States of Matter - When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and melt. The normal melting point of a crystal is the ..

When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and melt. The normal melting point of a crystal is the temperature at which it melts under one atmospheric pressure. Increase ..

Depending on the conditions of temperature and pressure, matter can exist in any of the three main states i.e., solid, liquid or gas. Matter can be inter-converted from one state to the other by the addition or removal of heat energy..

Solids Liquids Gases Particles are very closely packed thus rigid Particles are loosely packed thus can flow Particles are very loosely packed and can flow Voids are extremely small thus incompressible Voids are relatively larger thus slightly compressible Voids are v..
