A bottle in a chemical stockroom was labeled simply “dibromobenzene” without specifying which isomer was present. Gas Chromatography and TLC showed that it was a single pure compound, and the 'H- NMR spectrum showed 3 signals in the aromatic region that were a singlet, doublet and a triplet. You conclude that the bottle contained A) Br Br B) Br Br C) Br Br

Question 10 (1 point) Retake question Which of the following represents causality rather than association? Interest rates are higher in years ending with a 1 or a 6. Unemployment falls when the AFC champion wins the super bowl. In years that fashion dictates wider lapels on men's jackets, the stock market grows by at least 5 percent. Quantity demanded goes up when price falls because lower prices increase consumer purchasing power and because some consumers of substitute goods switch.
