Sudan-1 has a two-step reaction – diazotization and coupling reactions. Diazotization is the formation of diazonium salt‚ meanwhile‚ the coupling reaction took place when an activated aromatic compound‚ β-naphtol was reacted with the diazonium salt‚ benzene diazonium chloride‚ to form the azo compound known as the 1-phenylazo-2-naphthol. As a result‚ an orange-red precipitate was formed after series of reaction. Hence‚ all the said objectives in this experiment were achieved. INTRODUCTION Amines are

Global toluene prices also rose on the back of high benzene prices and continued strength in the xylene markets.” The 7% increase in benzene‚ a petrochemical used in packaging‚ various plastics

compounds of carbon and hydrogen which contain at least one hexagonal ring of carbon called as benzene in their molecule. Aromatic hydrocarbon can contain one or more than one benzene ring. Those compounds which contain more than one benzene ring are known as polynuclear aromatic hydrocarbon like naphthalene‚ anthracene etc. The aromatic compounds are generally taken as derivatives of benzene. Benzene and its derivatives are mainly used in synthetic organic chemistry. The main source of polynuclear

aromatic hydrocarbon‚ benzene‚ is compound out of just one such cycle; its formula is C6H6. The representation of benzene through a cycle of 6 carbon atoms with 3 double bounds was proposed by Kekule in 1865: In some special conditions‚ benzene can be hydrogenated‚ the result being a cyclic hexane: | +3H2 | | Under the influence of light‚ chlorine or bromine addition at the benzene’s molecule giving hexachlorocyclohexane: C6H6 + 3Cl2 C6H6Cl6. With ozone‚ the benzene gives a trizonide

CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached
