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 happens to Coenzyme A once Acetyl-CoA reacts to form citric acid?
Co enzyme A detaches and it goes to another acetyl group in the Pyruvate Oxidation
Why acetylene shows acidic character?
because it is an organic compound and its functional group is co-oh which is an acid so due to its acidic functional group its characteristics became acidic
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 does N stand for in N-acetylcysteine?
The N denotes the acetyl group attached to the nitrogen - taking place of the two hydrogens that were present before acetylation.
Why Acetic acid not used in acetylation?
Because it can not form the acetyl group easily but above 1000 Celsius acetic acid may form acetic anhydride which may be used to produce acetyl ion. Acetylation by acetic acid using is possible by using cobalt chloride as catalyst with good yield
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 structural formula of acetophenone?
Acetophenone is acetyl benzene, acetyl group attached to benzene ring ,C6H5-COCH3
The compound that actually begins the Kreb's cycle is?
Acetyl CoA (acetyl group) is the compound that enters the Kreb Cycle.
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 is an ynol?
An ynol is a compound having a hydroxyl group directly attached to an acetylene group.
What is an acetylhydrolase?
An acetylhydrolase is an enzyme which catalyses the hydrolytic removal of an acetyl group.
What happens to Coenzyme A once Acetyl-CoA reacts to form citric acid?
Co enzyme A detaches and it goes to another acetyl group in the Pyruvate Oxidation
What compound is produced by the transfer of the acetyl group of acetyl CoA to oxaloacetate?
Citric acid or citrate. The reaction is catalyzed by the citrate synthase enzyme.
What does chitin have in the glucose backbone?
In chitin's glucose backbone, each glucose molecule is attached to an amino group, turning each glucose molecule into glucosamine, and an acetyl group, turning each monomer into N-acetyl-D-glucosamine.
What is the chemical chloroacetophenone?
The -one suffix denotes this molecule - that contains a chlorine atom, an acetyl group, and some derivative of a phenyl group - as a hormone.
Why acetyl chloride hydrolyzed faster than benzoyl chloride?
The benzyl group acts as a protector retarding hydrolysis?
What is an acetyltransferase?
An acetyltransferase is another name for a transacetylase, an enzyme which catalyzes the transfer of an acetyl group from one molecule to another.
