Analysis of Oxygen Bearing Compunds
Analysis of Oxygen bearing Organic compounds
Abstract
The Unknown sample in the experiment can be tested to yield results such as 1° (primary), 2° (secondary), 3° (tertiary) alcohols. Tests such as the dichromate test, Tollen’s test, Lucas test, DNPH test and iodoform test would be very useful in determining the type of alcohol that the unknown sample belongs to. In the experiment, the unknown sample underwent series of testing to identify what property of alcohol it belonged to and the result was that it was a primary alcohol. It went through the Dichromate reaction, Tollen’s reaction and finally the Lucas reaction.
Introduction
“The analysis of oxygen bearing organic compounds” is an experiment in which a variety of tests are available to identify a compound’s property whether it is a primary, secondary or tertiary alcohol. The tests that are included to come up with such results are interconnected with one another like that of the Dichromate test, followed by the Tollen’s test to yield an aldehyde if positive for mirror coating. The second set of procedure would again start with The Dichromate test, followed by the Tollen’s test and finally the Lucas test to yield either primary alcohol if it became turbid or secondary alcohols as it’s result if it did not turn turbid. The last set of interconnected tests were that of again, the Dichromate test, Followed by the DNPH that would determine if the unknown sample is a Ketone (positive for red-orange precipitate) or a tertiary alcohol (if negative for red-orange precipitate). But before going deeper on what these tests are, what first are the difference between their results which are the primary, secondary and the tertiary alcohols, aldehydes and ketones? Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. Note however that there are different kinds of alcohols and Alcohols are categorized into different classes depending on how the -OH group is
