Introduction: In this experiment‚ when vinyl strip and acetate strip is rubbed by tissue‚ it will charge the vinyl strip negatively and acetate strip positively caused by the transfer of electron between the strip and tissue. If molecules have non zero bond dipole‚ because polar molecule must have a non-zero molecular dipole where electron spend more of their time closer to one atomic nucleus than the other and make one end partially positive or negative than the other end. Different charge will attract

classify organic compounds according to their functional groups. INTRODUCTION Organic compounds are the complex compounds of carbon. Because carbon atoms bond to one another easily‚ the basis of most organic compounds is comprised of carbon chains that vary in length and shape. Carbon atoms have four valence electrons that make them bond with each other easily. Thus organic compounds are classified according to their carbon chains that vary in length and shape. Hydrogen‚ nitrogen‚ and oxygen are

compounds. Bonding In Carbon:- The Covalent Bond Bond formed by sharing of electrons is called covalent bond. Two of more atoms share electrons to make their configuration stable. In this type of bond‚ all the atoms have similar rights over shared electrons. Compounds which are formed because of covalent bond are called COVALNET COMPOUNDS. Covalent bonds are of three types: Single‚ double and triple covalent bond. Single Covalent Bond: Single covalent bond is formed because of sharing of two electrons

Catenation The ability to form bonds between atoms of the same element. Carbon catenates to form chains and rings‚ with single‚ double and/or triple covalent bonds. Q.1 • Why does carbon form so many catenated compounds ? • Why does silicon undergo catenation to a lesser extent than carbon ? Homologous Series A series of compounds

Introduction: The chemical industry has become one of the largest manufacturing industries in the world since the beginning of the 21st century (Murmann‚ 2003). They convert raw materials such as oil‚ natural gas‚ air‚ water‚ metals‚ and minerals into more than 70‚000 synthetic chemicals (United States Department of Commerce‚ n.d.). Heavy demands on chemicals allowed prosperity of materials goods and had brought convenience for many people. Now they can be found everywhere around world‚ and even

Oscillating chemical reaction Aim: The overall reaction rate and concentrations of some reaction intermediates of certain chemical reactions oscillate‚ even in a homogeneous system. This phenomenon is commonly found in living organisms. These periodical variations occur when a feedback mechanism is available in which a product changes the reaction rate. In this experiment will produce oscillations in both time and space in the concentrations of cerium(IV) and cerium(III) in the BZ reaction. Use the
