    Experiment No. 1: MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting

As enzymes normally only catalyse one reaction the substrate has to fit in the specific shape (active site) and if it doesn’t fit in (lock and key method) then the enzyme won’t be catalysed. b.) As when the enzyme is denatured it’s special shape is destroyed‚ thus destroying it’s active site meaning that

    commonly used. In general they are made from fats and oils‚ which are hydrocarbons. These hydrocarbons are filtered and mixed with an alcohol‚ such as methanol‚ and a catalyst‚ resulting in a chemical reaction whose major products are biodiesel fuel and glycerol. Biodiesel fuel is light to dark yellow in color as a liquid. It’s insoluble in water‚ has a high boiling point and low vapor pressure. With such a high boiling point it is rather inflammable. It also has a density that is lower than water with

    mixture of many different molecules. A large part of these lipid makeups are usually a good amount of triacylglycercols which are literally the esters of three fatty acids bonded to a glycerol molecule. Variation in fatty foods are then caused by differences in chain length‚ degree of unsaturation‚ and position on the glycerol molecule(ACS). Another prominent factor when considering the different types of fats is that the unique profile of lipids present determines the exact nutritional as well as physiochemical
