canteen. Background information: Reducing sugars are any sugars that in basic solution forms some aldehyde or ketone. This allows the sugar to act as a reducing agent‚ for example in Benedict’s reaction. [1]Reducing sugars include glucose‚ fructose‚ glyceraldehyde‚ lactose‚ arabinose and maltose. All monosaccharides which contain ketone groups are known as ketoses‚ and those which contain aldehyde groups known as aldoses. Benedict’s reagent is used to determine if a reducing sugar is present

Introduction: According to chemists‚ hydrolysis is defined as the breaking of a compound involving a reaction with a water molecule. The goal of this experiment is to three-dimensionally show how disaccharides are transformed into monosaccharides using an acid-catalyzed hydrolysis reaction. For the purpose of this lab‚ it is quite useful to fully understand the following terms: optical rotation and carbohydrate. Optical rotation is measured by a polarimeter‚ which measures the polarization of light

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

Introduction An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils‚ ethereal oils or aetherolea‚ or simply as the "oil of" the plant from which they were extracted‚ such as oil of clove. Volatile oils are the odorous and volatile products of various plant and animal species. As they have a tendency to undergo evaporation on being exposed to the air even at an ambient temperature‚ they are invariably termed
