Adolf von Baeyer/Date of birth
Johann Friedrich Wilhelm Adolf von Baeyer was born on October 31, 1835, in Berlin, as the son of Johann Jakob Baeyer and Eugenie née Hitzig.
What was Adolf von Baeyer known for?
Notable among Baeyer’s many achievements were the discovery of the phthalein dyes and his investigations of uric acid derivatives, polyacetylenes, and oxonium salts. One derivative of uric acid that he discovered was barbituric acid, the parent compound of the sedative-hypnotic drugs known as barbiturates.
Why did Adolf von Baeyer win the Nobel Prize?
The Nobel Prize in Chemistry 1905 was awarded to Johann Friedrich Wilhelm Adolf von Baeyer “in recognition of his services in the advancement of organic chemistry and the chemical industry, through his work on organic dyes and hydroaromatic compounds.”

What does baeyer’s test indicate?
Baeyer’s reagent is a strong oxidizing reagent which is used to identify the presence of double or triple bonds in a hydrocarbon. Thus it indicates the unsaturation of hydrocarbon compounds.
What is Baeyer strain theory?
strain theory, in chemistry, a proposal made in 1885 by the German chemist Adolf von Baeyer that the stability of carbocyclic compounds (i.e., those of which the molecular structure includes one or more rings of carbon atoms) depends on the amount by which the angles between the chemical bonds deviate from the value ( …
What happens when ethene reacts with Baeyer’s reagent?
When ethylene reacts with Baeyer’s reagent, which is alkaline potassium permanganate solution, the product obtained is Ethylene glycol. to produce ethylene glycol which is a diol. Similarly in any type of butene, the product formed will be diol and the alcohol group will be attached to the carbons with double bonds.
What is the resulting color if positive with bromine test?
orange
For example, aldehydes are stated to give a positive result in the bromine test, which is when the compound turns the orange bromine solution clear. Figure 6.38 shows the reaction of two aldehydes with the bromine test: one gives a positive result (the left tube), and one gives a negative result (the right tube).
What is Sachse Mohr theory?
2. SACHSE-MOHR THEORY: In order to account for the stability of cyclohexane and higher members, Sachse and Mohr (1918) proposed that such rings can become free from strain if all the ring carbons are not forced into one plane, as was assumed by Baeyer.
What are limitations of Baeyer’s strain theory?
Limitations of Baeyer Strain Theory in Cycloalkanes According to Baeyer, larger ring structures are not feasible due to negative pressure, but they do exist and are very stable. To remove angle pressure, larger ring structures are wrinkled (puckered) rather than planar.
How do you turn an alkene into an alcohol?
Alkenes can be converted to alcohols by the net addition of water across the double bond.
Who was the father of Adolf von Baeyer?
J ohann Friedrich Wilhelm Adolf von Baeyer was born on October 31, 1835, in Berlin, as the son of Johann Jakob Baeyer and Eugenie née Hitzig. He came from a family distinguished both in literature and the natural sciences. His father, a lieutenant-general, was the originator of the European system of geodetic measurement.
When did Adolf von Baeyer win the Nobel Prize?
Like Berzelius and Liebig, von Baeyer distinguished himself by forming a school which alone nurtured fifty future university teachers. Honours were heaped upon him, including the Nobel Prize for Chemistry in 1905. On his fiftieth birthday he was raised to the hereditary nobility.
How old was Adolf von Baeyer when he discovered copper?
He discovered a double salt of copper at the age of twelve and barbituric acid while doing his post doctorate. When he was around thirty years old he started his experiments on indigo and worked at it for eighteen long years before he could find a suitable formula for its laboratory production.
When did Adolf Baeyer get the Davy Medal?
In 1881 the Royal Society of London awarded Baeyer the Davy Medal for his work with indigo. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1884.
