The study of structure of atoms, radioactivity, X-ray, diffraction, etc., in physics has enabled chemists to rearrange elements in the periodic table and to have a better understanding of chemical bonding and complex chemical structure..

In measurements approximation also plays an important role. In day to day practice we always use approximation. You must have heard people saying "It is approximately five minutes walk from the station" or "Both of them are more or less of the same height" etc. Approximations also play an importan..

The values of some important physical constants of the carbon fami1y are recorded in the below tab..

Heavy water is colourless, tasteless and odourless liquid. It has all higher values for physical constants than the corresponding values of ordinary water..

i) Physical state and smell - The lower members of the family are colorless liquids whereas the higher members are crystalline solids. They are stable compounds with pleasant smel..

Physical Change - A physical change is one in which the shape, size, appearance or state, of a substance may alter, but its chemical composition remains same. No new substance is formed. It is usually a change, which is reversible. By reversing the process, the original substanc..

A physical change is one in which the shape, size, appearance or state, of a substance may alter, but its chemical composition remains same. No new substance is formed. It is usually a change, which is reversible. By reversing the process, the original substance can be obtained. For e.g.,..

i) Physical state and smell - Lower members of aliphatic amines are gases while higher members are liquids. Among, aryl amines, lower members are liquids but higher members are solids. Methyl amine and ethyl amine have ammoniacal smell but higher amines have fishy smell. Most of the aroma..

Physical Properties - Being polar in nature, the acid derivatives have higher boiling points than hydrocarbons of comparable molecular masses. Acid chlorides, anhydrides and esters have nearly the same boiling points as the aldehydes and ketones of comparable molecular masses. Their boili..

Acetic acid is a colorless, corrosive liquid with a pungent smell at ordinary temperatures. But below 290K, it solidifies to an icy mass called glacial acetic acid. It boils at 391K and its specific gravity is 1.08 at 273K. It is miscible with water, alcohol and ether in all ratios. It is a good s..
