How does grignard reagent stabilized in ether solvent?

My teacher said me, “ether solvent stabilized grignard reagent by donating electron”. Is she right? can you explain in other way? I couldn’t understand this. I need help. plz help me.
thanx:-)

Is there always a limiting reagent in a chemical reaction?

5 star reward for the best answer.

How do chromosomes stain pink when stained with Schiff’s Reagent?

How do chromosomes stain pink when stained with Schiff’s Reagent?
Is it because of aliphatic ketones or aliphatic aldehydes?
If it is because of one of the above named, how does it happen?
Thanks a lot in advance! =D

Which of these reactants is the limiting reagent? What is the theoretical yield of zinc sulfate?

If 38 ml of 1. 8 M of sulfuric acid is mixed with 5. 21 g of zinc and allowed to react together. Question is above. Please show me steps thanks

What is the role of the limiting reagent in a chemical reaction?

Why is that a starch, which is a substance composed of many glucose molecules,is negative in Benedict reagent?

My conclusion is that starch is a polysaccharides not a glucose, so it would be hard for Benedict solution to break down the cluster of glucose in starch.
I am not sure about this, so I need to know if I was right or wrong. Please explain why.

How would you calculate the number of moles of product formed and the number of moles of excess reagent?

2Al + 3 (Cl)2 –> 2Al(Cl)3Given 3. 0 moles of aluminum and 5. 3 moles of (Cl)2 reactingThis is not a way for you to do my homework. . . I need to have an example for doing this sort of problem because I have more to do Thank You

Chem Question: How much of each reagent is needed?

I need to make 2g CeZrO4 from Ce(NO3)3 *6H20 and Zr(OCH2CH2Ch3)4 the Ce(NO3)3 *6H2O is in Crystals but the other is diluted to 70% by weight. I also need both reagents diluted to 1 Molar. How much of each reagent do I need to weight out and how do I dilute them?

Properties of a good drying reagent?

Just wondering, what are 3 properties of a good drying reagent?

How do you find how much of something is produced if you know the MW and reacting w/ excess reagent?

If I’m reacting x amounts of lauric acid with excess ethanol and the MW of the product is given.
thanks.
