How many moles of grignard reagent
WebCorrect option is A) Grignard reacts with unsaturated carbonyl compounds so two moles is required for each ester & carbonyl chloride. Grignard also reacts with acidic H so one mole for −OH and one mole for −SH. Last one mole is required to replace Cl− group. So total 7 moles of Grignard reagent is required. Was this answer helpful? 0 0 WebAnswer (1 of 3): It will depend, a bit, on your Grignard. When looking at the above molecule, there are three positions where a Grignard will hit: the nitrile position and both ester positions. You could imagine that, since there could be 6 additions (two per function), but I believe there will ...
