R-group from Grignard reagent(RMgX) is converted to corresponding alkane when G.R reacts with H2O, ROH, NH3 or CH3COOH.
Question#10
Grignard reagent is prepared by reacting ETEA2009
Question#11
Which is not true about Grignard reagent?                           ETEA2015 Med
Grignard reagent are very stable and can not be isolated from ethereal solution easily .
Ethers don't have acidic protons, so Grignard reagents are stable in ether.
