Why the reactions shown by grignard reagent are exothermic?
grignard reactions evolve heat
Provide methods for preparing the following compounds by the grignard method?
The Grignard reaction is when a solution of carbonyl is added to a Grignard reagent. Grignard reactions are slow or sluggish.
Why does addition of H2SO4 stop reactions?
H2SO4 is an acid, so when you add that to the catalase reactions, the pH drops below where the catalase can function. Acids have lower pH and therefore the catalase can no longer function, so the reaction stops.
What is the role concentrated h2SO4 in the hopkins-Cole test?

What is the role of h2SO4?
it can act as a catalyst, an acid, a dehydrating agent

Why only ethers are used as a catalyst in grignard reagent reactions?
Ethers are used as solvent in Grignard reaction and not as catalyst. This is because if we use other solvents which have acidic hydrogen, Grignard reagent will decompose and the Grignard reaction will not proceed further.
What has the author Roger Grignard written?
Roger Grignard is known for his works in the field of organic chemistry, particularly in the area of organometallic chemistry. He has made important contributions to the development of new synthetic methods and the understanding of metal-catalyzed reactions. Some of his notable research includes the Grignard reagents and Grignard reaction.
What has the author Thomas Joseph Gair written?
Thomas Joseph Gair has written: 'Reactions of azomethines with Grignard reagent'
What is the chemical reactions between grignard reagent and carbon dioxide?
RMgX + CO2 -> RCOO- + MgX + The next step is to add acid and form the carboxy acid RCOO- + H+ -> RCOOH So a grignard plus CO2 makes a carboxy acid.
