Hypothesis: I think that in this experiment the results of the boiling point of each sample is going be slighly different from what I found on Internet. aim: my aim is to look at what temperature and how long the following alcohol (methanol‚ I-butanol‚ Ethanol and Hexane) reach their boiling point and comparing the results that I found on internet and mine. Materials: Alcohol: Ethanol‚ I-Butanol‚ Ethanol and Hexane Four Test tubes (boiling tube) Test tubes holder Data logger Hot plates Bunsen

In the IUPAC system of nomenclature‚ functional groups are normally designated in one of two ways. The presence of the function may be indicated by a characteristic suffix and a location number. This is common for the carbon-carbon double and triple bonds which have the respective suffixes ene and yne. Halogens‚ on the other hand‚ do not have a suffix and are named as substituents‚ for example: (CH3)2C=CHCHClCH3 is 4-chloro-2-methyl-2-pentene. If you are uncertain about the IUPAC rules for nomenclature

The Chemistry of Cosmetics Cosmetics are an excellent example of how discoveries in chemistry are part of our day-to-day lives. In fact‚ just reading the composition of any common cosmetic can become a chemistry class: water‚ emulsifiers‚ preservatives‚ thickeners‚ pH stabilizers‚ dyes and fragrances‚ combined in different ratios‚ for different purposes. The use of cosmetics – that is‚ chemical compounds to improve our appearance – is not a recent phenomenon. It is said that the Egyptian queen Cleopatra

BACKROUND INFORMATION Organic chemistry is the study of hydrocarbons and their various deviations. (Ex. natural gas‚ paper‚ proteins‚ carbohydrates) Saturated hydrocarbons are hydrocarbons with carbon-carbon single bonds. (Ex. C-C) Unsaturated hydrocarbons are hydrocarbons with one of more multiple carbon-carbon bonds. (Ex. C=C double bond‚ triple bond‚ or both) Stereoisomers have the same molecular and structural formulas but different orientations of atoms in space. Constitutional isomers
