How is methane prepared from a Grignard reagent?
When the source of protons reacted to Grignard reagent it will definitely give respective alkane, therefore, the only molecule that will react with given Grignard reagent to give methane is ethaneamine.
How is methane prepared from CH3MgBr?
CH3MgBr on reaction with compounds having atleast once acidic hydrogen will evolve methane/CH4 gas. Replace the R’ group with any alkane and you will easily get 10 or more compounds which evolve methane gas on reaction with CH3-Mg-BR.
What is the mechanism of chlorination of methane?
The organic product is chloromethane. One of the hydrogen atoms in the methane has been replaced by a chlorine atom, so this is a substitution reaction. However, the reaction does not stop there, and all the hydrogens in the methane can in turn be replaced by chlorine atoms.
Which compound on reaction with CH3MgBr gives methane?
So, the correct answer is “Option D”. Note: Grignard reagents are highly reactive organic compounds and it can react with any source of proton to give hydrocarbons because acid base reactions are much faster than nucleophilic addition reactions.
How is methane converted to ethane?
Methane is first treated with chlorine gas in the presence of sunlight or ultraviolet. Here, methane gets converted into chloromethane. 2. Chloromethane is treated with sodium metal and dry ether to form the product ethane.
Which reaction is used to prepare alkanes?
Alkane can be prepared from alkene and alkyne through the process of hydrogenation. In this process, dihydrogen gas is added to alkynes and alkenes in the present catalyst. This catalysts which are finely divided is like nickel, palladium or platinum to form alkanes.
What is the importance of Grignard reagent?
Grignard reactions are important due to their ability to form carbon-carbon bonds. Grignard reagents are strong bases and will react with protic compounds which makes them exceedingly valuable tools for organic synthesis.
