  2. Bromine test - Wikipedia

    en.wikipedia.org/wiki/Bromine_test

    In organic chemistry, the bromine test is a qualitative test for the presence of unsaturation (carbon-to-carbon double or triple bonds), phenols and anilines. An unknown sample is treated with a small amount of elemental bromine in an organic solvent, being as dichloromethane or carbon tetrachloride. Presence of unsaturation and/or phenol or ...

  3. List of reagents - Wikipedia

    en.wikipedia.org/wiki/List_of_reagents

    is an alkaline solution of potassium permanganate; used in organic chemistry as a qualitative test for the presence of unsaturation, such as double bonds; N-Bromosuccinimide: used in radical substitution and electrophilic addition reactions in organic chemistry. Also acts as a mild oxidizer to oxidize benzylic or allylic alcohols.

  4. Assay - Wikipedia

    en.wikipedia.org/wiki/Assay

    The analyte can be a drug, biochemical substance, chemical element or compound, or cell in an organism or organic sample. [ 1 ] [ 2 ] An assay usually aims to measure an analyte's intensive property and express it in the relevant measurement unit (e.g. molarity , density , functional activity in enzyme international units, degree of effect in ...

  5. Matrix (chemical analysis) - Wikipedia

    en.wikipedia.org/wiki/Matrix_(chemical_analysis)

    In this technique, the response of the sample is measured and recorded, for example, using an electrode selective for the analyte. Then, a small volume of standard solution is added and the response is measured again. Ideally, the standard addition should increase the analyte concentration by a factor of 1.5 to 3, and several additions should ...

    -A simple example of the Evelyn effect is the sophomore level chemistry lab experiment involving two popular examples that are listed below. a) Dehydration of 4-methylcyclohexanol [2] Dehydration of 4-methylcyclohexanol.jpeg. b) Dehydration of 2-Methylcyclohexanol [4] Dehydration of 2-Methylcyclohexanol.jpeg

  7. Combustion analysis - Wikipedia

    en.wikipedia.org/wiki/Combustion_analysis

    Combustion analysis is a method used in both organic chemistry and analytical chemistry to determine the elemental composition (more precisely empirical formula) of a pure organic compound by combusting the sample under conditions where the resulting combustion products can be quantitatively analyzed.

  8. Organic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organic_chemistry

    Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]

  9. Condenser (laboratory) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(laboratory)

    In chemistry, a condenser is laboratory apparatus used to condense vapors – that is, turn them into liquids – by cooling them down. [1] Condensers are routinely used in laboratory operations such as distillation, reflux, and extraction. In distillation, a mixture is heated until the more volatile components boil off, the vapors are ...
