You will analyze the purity of propyl-p-tolyl ether by gc. assuming that some n-pr-i (starting material) is present, which compound, n-pr-i or propyl-para-tolyl ether (product), eluted from the gas chromatography column first (had the shorter retention time). explain the order of compound elution in terms of molecular structure and boiling point. 5. using the same experimental procedure as in this experiment, explain why using para-bromotoluene and sodium n-propanoxide (which in principle, would give the same product) would not work. assign all the 'h-nmr and 13c-nmr peaks on the spectra of propyl-para-tolyl ether p 325-326.

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.
