Thin layer chromatography TLC

Thin Layer Chromatography. Thin layer chromatography, or TLC, is a method for analyzing mixtures by separating the compounds in the mixture. TLC can be used to help determine the number of components in a mixture, the identity of compounds, and the purity of a compound.

Identification of an Unknown – Alcohols, Aldehydes, and ...

2,4-Dinitrophenylhydrazine : Aldehydes and ketones react with 2,4-dinitrophenylhydrazine reagent to form yellow, orange, or reddish-orange precipitates, whereas alcohols do not react. Formation of a precipitate therefore indicates the presence of an aldehyde or ketone. The precipitate from this test also serves as a solid derivative.

Synthesis of Cyclohexene The Dehydration of Cyclohexanol

Set up a fractional distillation apparatus in the same way as in the distillation experiment (remember the boiling chips). Be sure to use the distillation column (in some rare cases a slightly longer narrower glass tube that looks a lot like the distillation column may have inadvertently gotten mixed in to some of the lockers. Be sure to

Melting Points - University of Massachusetts Amherst

Melting Points. The temperature at which a solid melts is known as the melting point (MP) of that substance. The melting point is a physical property of a solid and can be used to help identify a substance. In practice, a solid usually melts over a range of temperatures rather than at one specific temperature.

A Brief Discussion of Color - BMB & Chemistry IT

A Brief Discussion on Color. Because several tests in the Alcohol, Aldehyde, and Ketone experiment involve color changes or produce colored compounds, a modest understanding of color will be helpful in the interpretation of the test results. What causes a compound to appear as being colored? The answer to this
