Please read question/answer choices carefully and answer ALL questions with a clear and simple explanation. Incorrect or Incomplete answers will not be given any credit (thumbs down). Thank you!Q1. Predict the order of elution of a mixture of benzyl alcohol, biphenyl, benzoic acid, and methyl benzoate from an Alumina column in column chromatography. AND WHY (SIMPLE EXPLANATION)Q2. Calculate the percent yield of Methyl nitrobenzoate, if 6 grams of Methyl benzoate produced 3 grams of Methyl nitrobenzoate during the nitration experiment. Q3. According to the news, the Mississippi River is polluted with toxic Dioxin. You have a pure sample of Dioxin. How do you determine that the news is true or not?Q4. Explain the Retention time, in GC. What will happen to retention time, if you increase the detector temperature?

Problem #3 (ch. 1, problem 15)the ideal gas law provides one way to estimate the pressure exerted by a gas on a container. the law isí‘ťí‘ť=푛푛푛푛푛푛푉푉more accurate estimates can be made with the van der waals equationí‘ťí‘ť=푛푛푛푛푛푛푉푉â’푛푛푟푟â’푞푞푛푛2푉푉2where the term nb is a correction for the volume of the molecules and the term an2/v2is a correction for molecular attractions. the values of a and b depend on the type of gas. the gas constant is r, the absolutetemperature is t, the gas volume is v, and the number of moles of gas molecules is indicated by n. if n = 1 mol of an ideal gas were confined to a volume of v = 22.41 l at a temperature of 0â°c (273.2k), it would exert a pressure of 1 atm. in these units, r = 0.0826.for chlorine gas (cl2), a = 6.49 and b = 0.0562. compare the pressure estimates given by the ideal gas law and the van der waals equation for 1 mol of cl2 in 22.41 l at 273.2 k. what is the main cause of the difference in the two pressure estimates, the molecular volume or the molecular attractions?
