CHEMICALS IN MEDICINE AND HEALTH CARE Chemotherapy Chemical substances of natural or synthetic origin which are used for curing diseases and reducing suffering from pain are called medicines or drugs. The branch of science which deals with the…
INTRODUCTION Chemical Kinetics is the branch of science that deals with rate of reaction, factors affecting the rate of reaction and reaction – mechanism. Different reactions occur at different rate. In fact a chemical reaction involves redistribution of bonds ––…
INTRODUCTION It is an experimental fact that most of the process including chemical reactions, when carried out in a closed vessel, do not go to completion. They proceed to some extent leaving considerable amounts of reactants & products. When such…
CHEMICAL BONDING INTRODUCTION A molecule is formed if it is more stable and has lower energy than the individual atoms. Normally only electrons in the outermost shell of an atom are involved in bond formation and in this process each…

INTRODUCTION Alkyl halides or halo alkanes are compounds in which a halogen is bonded to an alkyl group. They have the general formula RX (where R is alkyl group CnH2n+1) X is halogen atom. Alkyl halides are classified as primary,…
CARBONYL COMPOUNDS INTRODUCTION Both aldehydes & ketones contain carbonyl group as their functional group. Structure of carbonyl group Both aldehydes & ketones have carbonyl group as the functional group. The carbonyl carbon is sp2 hybridised & it uses sp2 hybrid…
