Why "acetylene"?
Why is the compound even called acetylene at all?
I see no similarities to the acetyl radical. No methyls, no carbonyls (not even an oxygen atom), nothing.
The OED gives the etymology as [f. ACETYL + Gr. -ηνη female descendant, weaker derivative: see -ENE.
The Oxford Dictionary of English gives the origin as: mid 19th cen.: from acetic acid + -yl + -ene.
Acetylene can be hydrated to acetaldehyde, which contains the acetyl group and may account for the name. Acetyl compounds could, in principle at least, be dehydrated (often a facile reaction, no change in oxidation state) to C2H4 - an unsaturated hydrocarbon (hence -ene) from an acetyl group, hence acetylene.
What else can I help you with?
Is the acetyl group positively or negatively charged?
The acetyl group is not charged, it is neutral.
What is the mechanism of synthesis of acetyl glycine from glycine?
Acetyl glycine is synthesized by combining glycine with acetyl-CoA in a reaction catalyzed by the enzyme glycine N-acyltransferase. This enzyme transfers the acetyl group from acetyl-CoA to the amino group of glycine to form acetyl glycine.
What is the charge of an acetyl group in a chemical compound?
The charge of an acetyl group in a chemical compound is neutral, meaning it has no overall positive or negative charge.
What are the examples of alkynes?
Alkynes are a similar functional group to alkanes and alkenes. The difference is that alkynes have a triple bond between two carbon atoms. The most well known alkyne is Ethyne (Acetylene) . Its structure is H-C///C-H . This gas is used in oxy-acetylene burners, and produces a very hot flame to melt metals. Other alkynes are Propyne ; H-C///C-CH3 But-1-yne ; H-C///C - CH2-CH3 But-2-yne ; H3C-C///C-CH3 Be careful when spellings these chemcial names , there is only ONE letter difference. alkAne, alkEne, & alkYne.
What happens to Coenzyme A once Acetyl-CoA reacts to form citric acid?
Once acetyl-CoA reacts to form citric acid in the citric acid cycle, Coenzyme A is released and recycled to pick up another acetyl group for further energy production. The citric acid molecule then goes through a series of reactions in the cycle to produce energy in the form of ATP and reducing equivalents NADH and FADH2.
Is the acetyl group positively or negatively charged?
The acetyl group is not charged, it is neutral.
What is the chemical dicarbon hexahydride?
C3h6
What number of carbon atoms are in acetyl CoA?
23. 2 are from the acetyl group and 21 are from coenzyme A.
What is the mechanism of synthesis of acetyl glycine from glycine?
Acetyl glycine is synthesized by combining glycine with acetyl-CoA in a reaction catalyzed by the enzyme glycine N-acyltransferase. This enzyme transfers the acetyl group from acetyl-CoA to the amino group of glycine to form acetyl glycine.
What is the charge of an acetyl group in a chemical compound?
The charge of an acetyl group in a chemical compound is neutral, meaning it has no overall positive or negative charge.
What is the name of the compound c2h5cocl?
The compound C2H5COCl is called ethanoyl chloride or acetyl chloride. It is an organic compound commonly used in organic synthesis reactions to introduce an acetyl group into molecules.
What is an ynol?
An ynol is a compound having a hydroxyl group directly attached to an acetylene group.
What does pyruvate change to in respiration?
It splits into a two-carbon acetyl group, which is added to Coenzyme A to make Acetyl-CoA, and a CO2.
What compound is produced by the transfer of the acetyl group of acetyl CoA to oxaloacetate?
The compound produced by the transfer of the acetyl group of acetyl CoA to oxaloacetate is citrate, which is the first step in the citric acid cycle (Krebs cycle). This reaction is catalyzed by the enzyme citrate synthase.
What is an acetylhydrolase?
An acetylhydrolase is an enzyme which catalyses the hydrolytic removal of an acetyl group.
How many molecules of FADH2 are produced by the complete oxidation of one acetyl group by the citric acid cycle?
One acetyl group produces 1 molecule of FADH2 in the citric acid cycle.
