Chemistry 1 Revision Booklet Unit Chemistry 1 Syllabus At the beginning of each sub-section‚ activities are stated which develop candidates. skills‚ knowledge and understanding of how science works. Details are then given of the substantive contexts in which these skills‚ knowledge and understanding should be set. It is expected that‚ where appropriate‚ teachers will adopt a practical approach‚ enabling candidates to develop skills in addition to procedural knowledge and understanding. Note that

any other electrophilic organic compound to produce alcohols‚ which makes it important in laboratories. Organometallic reagents are strong bases that readily abstract a proton from H2O to form hydrocarbons because H2O is a stronger acid than the alkane product of the acid-base reaction. Similar reactions occur with the O-H proton in alcohols and carboxylic acids. Because of this‚ at the very beginning of our experiment‚ moisture was removed as it would react with our highly basic Gringard Reagents

Chromic acid was used in this experiment to in order to prepare 2-butanol. Cr (VI) is rather orange‚ but Cr (III) is dark green - therefore by oxidizing the alcohol (2-butanol)‚ an orange Cr (IV) is reduced to green. NMR and IR tests were taken to determine the result‚ and the crystallized derivative of

Introduction Reduction/Oxidation (Redox) reactions are ones that change the oxidation state of a compound. The oxidation state refers to the acquired charge (gained or lost electrons) of an element in relation to its original charge (i.e. S + 2e- S2+); in a compound‚ the overall oxidation state is calculated by adding all the charges of the elements present. The addition of electrons makes the element “reduced” and the loss of electrons is called “oxidized”. These reactions can be carried out
