WebAlcohol dehydration by elimination of water is central to a series of functional group interconversions that have been proposed as a reaction pathway that connects hydrocarbons and carboxylic acids under geochemically relevant hydrothermal conditions such as in sedimentary basins. Web28 dec. 2024 · One of these hydrogens is strongly attracted to the carbon-carbon double bond. The pi part of the bond breaks and the electrons in it move down to make a new bond with the hydrogen atom. That forces the electrons in the hydrogen-oxygen bond down entirely onto the oxygen. Note: It is easy to see why the oxygen carries a negative charge. fairfax county immersion lottery
