Why do you think that reactions involving Grignard reagents are sometimes carriedout in an atmosphere of nitrogen or argon?3. A Grignard reaction was performed and the following 1 H-NMR (90 MHz in CDCl 3 )was obtained of the purified product. Deduce the product's structure (MolecularFormula = C 7 H 6 O 2 ). Also write the overall reaction for its formation from anyorganohalide and carbonyl compound.1 H-NMR Spectral Data:Signal # Shift Integrat'n Splitting Comment #Neighbour H Signal Assignment1 7.5 3H2 8.1 2H3 12.1 1H Xchngs with D 2 O73
