A grignard reagent is an organic molecule attached to a groups such as MgBr. Look here: http://www.chemguide.co.uk/organicprops/haloalkanes/grignard.html

Thanks Peter! But I don't really understand when I'm allowed to use it. I study about alcohols for my final exams in Organic Chemistry..... do you know when can I use it as well?

anonymous · Answer

Grignard reagents react with carbon dioxide, aldehydes, and ketones. They can be used to extend carbon chains in organic processes.
All this and more is contained on the page I linked you to. Go read it.

Grignards have to be used in an aprotic solvent. This is extremely important. So you can't ever prepare or react anything with a Grignard that can act as an acid or a base, otherwise your reaction will fail. So with regard to your alcohols, what normally happens is something like:

|dw:1400491031784:dw||dw:1400491087276:dw| Then you protonate that with an acid to get an alcohol.
