of any substance.When you break up a molecule of water,for example,you no longer have water at all,but only the atoms of which water is made--one atom of oxygen and two of hydrogen.The moleules of living things are made,not of two or three atoms,but of hundreds or thousahds in ...
One mole of propionic acid ( I ) reacts with 2 mol of 1,2‐butylene oxide ( II ) in the presence of lithium naphthalenide to give 4‐hydroxy‐2‐(2′‐hydroxybutyl)‐2‐methylhexanoic acid ( V ), which can be easily converted into 2‐(2′‐hydroxybutyl)‐2‐methyl‐4‐ethyl‐γ‐...
