- Hemoglobin is 6.0% heme (C₃₄H₃₂FeN₄O₄) by mass. Toremove the heme, hemoglobin is treated with acetic acid andNaCl to form hemin (C₃₄H₃₂N₄O₄FeCl). At a crime scene, ablood sample contains 0.65 g of hemoglobin. (a) How manygrams of heme are in the sample? (b) How many moles of heme?(c) How many grams of Fe? (d) How many grams of hemincould be formed for a forensic chemist to measure?Circle the chiral carbons in the following compounds:Owing to their structural similarity, separation of mixtures of organic compounds (such as the isomers 1-t- butyl-, 3-t-butyl-, and 4-t-butylcyclohexene) often proves difficult. Silica gel chromatography, however, can be used with some success provided that sufficient silica gel is used to provide optimal separation. Consider, for example, the TLC plate pictured at right after developing and UV visualization where prior to elution, lanes A and B were spotted with 1-t-butylcyclohexene and lanes B and C spotted with 4-t- butylcyclohexene. Which of the following must be true? In the space provided, indicate the CORRECT answers (as 1, 2, and/or 3) then explain your reasoning for all three statements. 1. 1-t-butylcyclohexene elutes faster than 4-t-butylcyclohexene. 2. The R; for both 1-t-butylcyclohexene and 4-t-butylcyclohexene are equal. 3. 4-t-butylcyclohexene is less polar than 1-t-butylcyclohexene
