Thin-layer (TLC) is a chromatographic technique that is useful for separating organic compounds. Because of the simplicity and rapidity of TLC, it is often used to the progress of organic reactions and to check the purity of . Method Thin-layer consists of a stationary phase immobilized on a or plas...

Iron(III) Chloride - Pyridine Test Chemical properties Identification of phenols. A. All phenols react with iron(III) chloride solution to form a color compounds. Phenols with one hydroxy group form a violet compounds, phenols with two OH- groups – blue compounds, thymol does not react with iron chl...

2,4-DNP Test for Aldehydes and Ketones Chemical properties Carbonyl Group The carbonyl group in aldehydes and ketones reacts with hydrazine and its derivatives. The compound most frequently used is 2,4-dinitrophenylhydrazine because the product is always a solid. When 2,4-DNP is used as a solution i...

alkyne Bromine in Carbon Tetrachloride Chemical properties Bromine will add to the carbon-carbon double bond of alkenes to produce dibromoalkanes and with alkynes to produce tetrabromoalkanes. When this reaction occurs, molecular bromine is consumed, and its characteristic dark red‑brown color disap...

Carboxylic Acids Chemical properties Determination of Equivalent Weight (or Neutralization Equivalent) Molecular Weight Determination Generally, any acid (or base) can be titrated using standard solutions of base (or acid). The neutralization equivalent obtained is usually a simple fraction of the m...
