Hydroxides andhydroxylThere are essential differences: (1) hydroxyl is a group ion composed of H and O, hydroxyl is a group atom composed of H and O, (2) hydroxyl is always equivalent to a separate ion, while hydroxyl is sometimes equivalent to a separate atom, and sometimes it can be disassembled, for example, 2C2H5OH+2Na==2C2H5ONa+H2
In addition to its own hydrogen and oxygen atom bonding, hydrogen and oxygen also have an electron from the outside, so that both atoms in the hydrogen and oxygen radical reach the outermost saturated structure, so that hydrogen and oxygen radical can exist in large quantities in the solution independently and stably;
The hydroxyl group is only bound by its own hydrogen and oxygen atoms, but also lacks an electron to reach saturation, so it mustfunctional groupForm and othersAtomic clusterThey are combined and cannot exist stably alone.
