What are the only types of alkynes which can form acetylides?
Terminal alkynes, which have a triple bond at the end of the carbon chain, are the only types of alkynes that can form acetylides. Internal alkynes, which have a triple bond between two carbon atoms in the middle of the carbon chain, do not readily form acetylides.
Why formaldehyde use in mannich base formation?
Formaldehyde is used in Mannich base formation as a source of a reactive carbonyl species that can react with an amine and an enolizable compound to form the Mannich base. The formaldehyde provides the carbonyl functional group necessary for the reaction to occur, leading to the formation of aminomethylated compounds with potential pharmaceutical or synthetic applications.
Use Hess's law or the above equation to find the heat of solution when potassium sulfate is dissolved in water?
To find the heat of solution when potassium sulfate is dissolved in water, you can use Hess's law. This involves adding the heats of formation of the products and subtracting the heats of formation of the reactants. You can use the enthalpies of solution of potassium ions and sulfate ions to calculate the overall heat of solution for potassium sulfate.
How do you calculate the enthalpy of formation for a chemical compound?
To calculate the enthalpy of formation for a chemical compound, you subtract the enthalpies of formation of the reactants from the enthalpies of formation of the products. This gives you the overall change in enthalpy for the reaction, which represents the enthalpy of formation for the compound.
Is the reaction mechanism affected by the use of a stabilized ylide versus an unstabilized ylide in the formation of a Wittig reaction product?
Yes, the reaction mechanism is affected by the use of a stabilized ylide versus an unstabilized ylide in the formation of a Wittig reaction product. Stabilized ylides are more reactive and form the desired product more efficiently compared to unstabilized ylides.
What are the only types of alkynes which can form acetylides?
Terminal alkynes, which have a triple bond at the end of the carbon chain, are the only types of alkynes that can form acetylides. Internal alkynes, which have a triple bond between two carbon atoms in the middle of the carbon chain, do not readily form acetylides.
Why lithium do not form acetylide but sodium form acetylide?
Lithium's small size and high charge density make it more likely to form stable ionic compounds rather than covalent compounds like acetylides. Sodium, with a larger size and lower charge density, is more likely to form covalent bonds, allowing it to form acetylides.
The best convoy formation to use with inexperienced or foreign drivers is the?
file formation
How do you use transform and formation in a sentence?

How do you use cell formation in a sentence?
You cannot imagine the structure of cell formation until you see it under a microscope.The cell formation contained abnormalities.Cell formation increases dramatically in cancers.
What bond formation does covalent use?
covalent bonds
How does a eukaryoyic cell use instructions from the nucleus to make proteins?
by transcription(formation of mRNA) and then translation( formation of polypeptide/protein)
What type of battle stratiegies did ancient Greece use?
the battle formation that ancient Greece used was called the phalanx formation.
Which step has not been accomplished by scientists studying the origin of life?
formation of protocells that use RNA to reproduce themselves
Why use stratigraphic range chart?
becon range of formation use range stratigraphy chart
What kind of in formation or items did he use for his theory?
What kind of information or items, did he use to support his theory
How you use the word formats in a sentence?
