2-Ethoxy-2, 3-dimethylbutane reacts with concentrated aqueous HI to form two initial organic products A and B. Further reaction with HI produces organic product C from product B. Illustrate the structures of these three products.
A 0.7120g specimen of iron ore was brought into solution and passed through a Jones reductor. titration of the Fe(II) produced required 39.21 mL of 0.02086 M KMnO4. express the results of this analysis in terms of (a) percent Fe and (b) percent Fe..
Ethanol, C2H5OH, boils at 78.29 degrees celsius. How much energy, in joules, is required to raise the temperature of 1.00 kg of ethanol from 20.0 deg C to the boiling point and then to change the liquid to vapor at that temperature.
