Draw the major organic product for (2R,3S)-2-bromo-3-methylpentane reacting with the given nucleophile. Indicate stereochemistry if necessary, including H\'s, at each stereogenic center. You do not have to draw any reaction by-products (just draw the major organic product formed from this reaction). You have to draw the product as a correct skeletal structure.
The reaction of coal with water at high temperatures produces synthesis gas, which is a mixture of carbon monoxide and hydrogen. Use the bond energies in the table below to estimate the enthalpy of the reaction
