GR is used in Alkylation, in coupling reactions, for making Esters of Different Functional Groups, Aromatic & Tertiary Thiols etc.

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.
By using grignard reagent
During the formation of Grignard's reagent dry or anhydrous ether is used to prevent the magnesium from moisture because in presence of water magnesium leaves the organic material and combines with water.
yes it does CH3MGBR formulae of Grignard rea.
wurtz synthesis: 2CH3Cl + 2Na = CH3-CH3 + 2NaCl Grignard Synthesis: - Preparation of Grignard reagent: CH3Cl + Mg = CH3MgCl - Hydrolysis of Grignard reagent: CH3MgCl + HCl = CH3-H + MgCl2

Because it is a polar solvent and highly reactive towards Grignard's reagent forming the alkanes.
Yes
The Grignard reaction is when a solution of carbonyl is added to a Grignard reagent. Grignard reactions are slow or sluggish.

you react the grignard with either an ester, an acid chloride or a ketone to get a tertiary alchohol. if you react a grignard reagent with an aldehyde you get a secondary alcohol and if you react the grignard with formaldehyde (methenal) you get a primary alchohol. same thing happens if u use R-Li instead of a grignard reagant.
Yes, it results in a Grignard reagent.
Grignard reagent is a organometallic compound in which the divalent magnesium is directly linked to an alkyl group and a halogen atom.
