Rcn with 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 WebGrignard reagents are used synthetically to form new carbon–carbon bonds. A Grignard reagent has a very polar carbon–magnesium bond in which the carbon atom has a partial negative charge and the metal a partial positive charge. The polarity of the carbon–magnesium bond is opposite that of the carbon–halogen bond of haloalkanes.
