What is Principle behind using orcinol reagent in extraction of RNA from yeast?
The method depends on conversion of the pentose, ribose in the presence of hot acid to furfural which then reacts with orcinol to yield a green color. The color formed largely depends on the concentration of HCl, ferric chloride, orcinol, the time of heating at 100°C etc up to certain maxima.
Contribution of Johann Dobereiner for the periodic table?
An organized tabular arrangement of chemical elements on the basis of their electron configurations, atomic number and recurring chemical properties is the periodic table of elements. Johann Wolfgang Dobereiner has a great contribution in periodic table of elements because he foreshadowed the periodic law for the chemical elements.
How many dehydration reactions occur in the conversion of a molecule of an aldopentose to furfural?
three
Why is sulphuric acid used in molisch test?
sulphuric acid acts as a dehydrating agent.all carbohydrates are dehydrated to give dehydration products. For example, pentoses give furfural as dehydration product where as hexoses give 5-hydroxy furfural.. these are attacked by 1-napthol to give a purple coloured condensation product...

What is furfural?
Furfural is furan-2-carboxaldehyde, a heterocyclic aldehyde. A colorless, sweet-smelling, mobile liquid, C4H3OCHO, made from corncobs and used in the synthesis of furan, as a solvent for nitrocellulose, and as a fungicide and weed killer.

What measures are to be taking to check losses in furfural at the furfural extracting unit of a refinery?
Our company is an overseas department of Spring Strength Group, who is the earliest specialized manufacturer of furfural in China. With annual productivity of 5,000 MT, our factory manufacture a mass of furfural with content of 99%,98.5%.For the advantages of low-price, high-quality and good-service, our products have long enjoyed a great fame both at home and abroad and we are in the belief that you will be pleased with them.
Is furfaral an acid?
No. It is an aldehyde. Furfural is furan-2-carboxaldehyde.
What is the structure of the adduct of 2 molecules of resorcinol with 1 molecule of furfural?
This process is the identification of carbohydrates. One may draw the structure of the adduct two molecules of resorcinol with 1 molecule of furfural to obtain carbohydrates.
