5. Anesthetic gases used in surgery are known to bind to the hemoglobin molecule in red blood cells. The diagram below illustrates O2 binding curves of normal human HbA in the presence of the anesthetic gas dichloromethane (DCM). O UNTREATED 100 Symbols: a Dсм 23 Torr • DCM 50 Torr x DCM I00 Torr o, 0 Torr DCM; О, 23 Torr DСМ Д, 50 Torr DСМ x, 100 Torr DCM. 80 60 40 (1 Torr = 1 mm Hg.) 20 The solutions were buffered to pH 7.4. 0.5 1.0 1.5 2.0 log p02 For the curves at 0 and 100 Torr of dichloromethane, draw their equivalent in the form of (a) (* Hill plots. Label the axes and indicate on both the plot above and the Hill plot where the value of the dissociation equilibrium constant Kd for O2 binding is defined for 0 and 100 Torr of dichloromethane Kd Hb(O2)n nO2 Hb + Be sure to label the axes, indicate the units on both axes, and make the Hill plot so that the values of Kd are equivalent to those on the saturation plot above.

In the following questions, consider the carbanion formed by the arrow pushing below: он | HC-C-R H ཋཙམཏིཏཡརིཡཐཱ པཱལཾ ཏིཡཏིཡ, B: H C-C-R Н Question 7 2 pts Below are a proposed resonance structure of the carbanion and rules of resonance. Which rules, if any, does the resonance structure break? (Select all that apply.) Ο Η | │ C-C-R H The formal charge of the molecule cannot change. ☐ Single (sigma) bonds cannot be broken. With the exception of carbocations, octet rules must be satisfied. ☐ All of the above rules are satisfied.
