What is the HOMO for C2
What is the exact mass in Dalton, mass errors in ppm, estimated carbon number from isotopic abundance and ionic formula for the flw ESI MS peaks m/z: 104.3, 117.8, 155.9, 258, 276,296.2, 309, 542.9,705.6 and 867.1
Calculate the mass of Na2O that forms if 4,8g O2 reacts completely with sodium
Lamivudine is a drug used for the treatment of HIV (AIDS). This drug stop HIV from infecting cells in the body. Only the (-)-enantiomer of lamivudine is registered for the treatment of HIV because it is more active and less toxic than either the (+)-enantiomer or the racemate. In the (-)-enantiomer, the chiral centre at position 2 has the R configuration and the chiral centre at position 5 has the S configuration. Draw the structure of (-)-lamivudine using hashed and wedged line notions that represents R configuration at 2 and S configuration at 5. Need to show your work-up.
why the ionic radii for S2- is larger than O2-
