Chem 3418 Organic Chemistry Laboratory I Acid Base Review Definition In general‚ an acid is a substance that can donate a proton (H+) and a base is a substance that can accept a proton. Any proton in an organic molecule can potentially be donated. The most acidic proton in a molecule would be donated first. Any lone pair in an organic molecule can act as the proton acceptor. An acid (HA) reacts with a base (in this case H2O) to form the conjugate base of the acid (A-) and the conjugate acid of the

It can be administered orally‚ rectally or by intravenous route. (6) Benzene ring Carboxylic acid Ester Alkane Aspirin has a pKa of 3.49 and a melting point of 138-140 degrees Celsius. Aspirin molecule’s are insoluble in water that is why it must be sold in a solid form‚ there are no liquid forms of aspirin available. Aspirin is ionised in the stomach. Aspirin

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

Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard

Preparation of Synthetic Banana Oil Introduction: In this lab the synthesis‚ purification‚ and characterization of isoamyl acetate‚ or banana oil‚ was determined. The synthesis was completed by a reversible esterification reaction which required the heating of glacial acetic acid and isoamyl alcohol‚ combined with a sulfuric acid catalyst in hexane. In order to increase the efficiency of the reaction‚ LeChatelier’s Principle is utilized by removing water from the products. As a result‚ the reaction
