- Below you will find five reaction products (labeled product 1, product 2, etc.), but you will only find four reaction schemes. Your job is to match the reaction scheme with the correct product. Simply fill in the blank with the product number (i.e. 1,2,3,4, or 5). Then, state the regio-control that governs the reaction (i.e. Markovnikov or anti-Markovnikov). If the reaction does not have any regio-control then enter none. OH X Product 1 iocontrol: Product 2 1. Hg(OAc)2, H₂O 2.

- Certain amount of pure charcoal (carbon) has to be burnt with supplied natural air. Process engineer allowed exact amount of air required to burn the entire charcoal completely to carbon dioxide. Carbon has no reaction with nitrogen gas present in the air. In the reaction outlet if 5 kg of nitrogen gas was found, calculate the amount of charcoal used. (12C, 16O, 14N)At 0 oC, the solubility of sodium acetate in water is 36.1 g per 100 g of water and at 40 oC, the solubility is 66.4 g per 100 g of water.

Since all the products have the same molecular weight, you can closely approximate the density of the product mixture by averaging the densities of the products. Using the average product density, determine the theoretical yield in mL when 1.5 mL of 3,3-dimethyl-2-butanol and 7 drops of H2SO4 (conc) are heated together at 70°C.An inexperienced graduate student moved into a laboratory and began work. He needed some diethyl etherfor a reaction, so he opened an old, rusty 1-gallon can marked “ethyl ether” and found there was half a gallon left. To purifythe ether, the student set up a distillation apparatus, started a careful distillation, and went to the stockroom for the otherreagents he needed. While he was at the stockroom, the student heard a muffled “boom.” He quickly returned to his lab tofind a worker from another laboratory putting out a fire. Most of the distillation apparatus was embedded in the ceiling.(a) Explain what probably happened.(b) Explain how this near-disaster might have been prevented
