A 10 cm 3 air saturated Fricke dosimetry solution in a 1 cm diameter tube is irradiated for 10 min in a 6~ source of gamma rays. The optical density measured at 304 txm in a 1 cm light path at 30~ was 0.260 after the completion of irradiation and 0.003 before irradiation. (a) What is the total dose in gray absorbed by the solution?(b) If 10 cm 3 of methanol is irradiated in the same tube for the same 10min, what is the absorbed dose in gray. The Z/A for methanol is 0.562 and that for the Fricke dosimeter is 0.553. Explain any assumption you make to solve the problem.

Using mass spectrum and H+NMR, propose a compound containg C doubled bonded to O and C bonded to H (sp3)
What would be the signal, chemical shift, integration, or splitting? And what's the product structure draw an image of this.
Construct a simulated ¹ H NMR spectrum for 2-chloropropane. Drag and drop the appropriate splitting patterns into the boxes on the chemical shift baseline, and add integration values above each signal. Splitting patterns and integrations may be used more than once. Peak heights do not represent integration values. 7 1H 5 4 Answer Bank 4H 3 5H 2 6H 1 2H 0 ppm 3H
