Hey guys!

I need your help!!! so I'm looking at Destroyer Orgo section #1 and #139. They both are asking about Grignard reaction. #1 is asking which would most easily be converted into a Grignard Reagent and #139 is asking which would NOT react with ethylmagnesium chloride (grignard reagent) and both of their answers are Ether! so is grignard reagent reactive with ether or no? I thought it wouldn't.

Help pleaseee!!!!

I'm also majorly confused on #209 too (proton NMR). anyone knows a website with a nice explanation on H NMR and C NMR?

Thank you so much!

Ethers (non-epoxides) are unreactive to just about everything except strong acid.

i think the answers explained it pretty well, the reason why it's easy to FORM a grignard with ethers is because they don't react with grignards.

Now if you got all those protic stuff like... -OH and -COOH etc. how do you form grignards? they will form and immediately get destroyed. that's why in #1, the only logical answer was the ether

hope that helps

check wiki.

Typical solvents are diethyl ether and tetrahydrofuran. Oxygen and protic solvents such as water or alcohols are not compatible with Grignard reagents.
