in inorganic and metal organic chemistry

Acids, Bases and Salts indicators An indicator is a substance which shows the presence of a chemical substance by changing colour. A commonly used acid-base indicator is a litmus paper. Acids turn blue litmus red and bases turn red litmus blue. Methyl orange and phenolphthalein are other common indicators. Prope..

Organic Compounds Organic Chemistry The chemistry of the hydrocarbons and their derivatives is termed as organic chemistry. Allotropy The phenomenon of existence of two or more forms of an element having different physical properties but almost similar chemical pr..

Traditionally, chemistry has been divided into three branches - organic, inorganic and physical chemistry. Organic chemistry is the study of compounds of carbon. Inorganic chemistry is the study of compounds of all other elements and a few compounds of carbon. P..

Essay Type Questions 1. What is vital force theory ? Is it still used as a basis to classify Organic and inorganic compounds ? It not, why ? 2. How is organic chemistry defined now ? Give reasons as to why compounds are classified into organic and inorganic compounds ? ..

Organic compound Inorganic compound ]. Presence of carbon: Carbon is a necessary element in every organic compound. Carbon is not an essential element in inorganic compounds. 2. Solubility in water : They generally do not dissolve in water. They general..

36. The wrong statement about transition elements is (1) they are all metals (2) they form complex compounds (3) they show variable valency differing by two units (4) they form coloured compounds 37. The primary valency of Co in [Co(NH 3 ) 4 Cl 2 ]Br is (1) two (2) six (3) three (4) four 38. In which of the foll..

(1) stability of various oxides versus temperature (2) free energy of various oxides versus temperature (3) enthalpy of combustion of fuels versus temperature (4) internal energy of various oxides versus temperature 7. Which of these following plots indicates variation of free energy of formation of C02 with temperature? 8..

. Since then thousands of organic compounds of natural origin have been synthesized. It has now been established that the central atom in organic compounds is carbon and therefore organic chemistry is regarded as the study of carbon compounds. Certain carbon compounds which are obtained from non-living sourc..

What are the chief constituents of air? Which is present in greater percentage? 12. What are the common pollutants present in air? Mention their sources. 13. Wr..

Water, various salts and metallic ions occur as inorganic substances in cells. Water In the constitution of any living organism, 65 % or more water occurs. In living cells, it may be 70 to 90%. Let us study important properties of water and their relation to life. Compared to any other solvent, wat..
