Hydroboration conceptual question (LIFESAVER) an advantage of the hydroboration reaction is that rearrangement of the carbon skeleton does not occur. This lack of migration contrasts with results obtained upon the addition of hydrogen chloride to the double bond. Offer an explanation for the differnece in these results. PLEASE BE SPECIFIC! LIFESA…
salts in hot packs/coldpacks It is a scientific fact that heat energy is required to seperate the associated ions in a solid salt, and heat energy is released when water molecules surround (solvate) the ions. MgSO4 is one of the best salts as a possible hot pack. Epsom salt, MgSO4 x 7H20, is used for […]
