None of them are coincidences. They all follow from a single fact: the bent V shape of three atoms, and the hydrogen bonds that follow from it. The entire chemistry of life depends on this shape. The Science Behind Water Water's structure is deceptively simple: two hydrogens bonded to one oxygen at a 104. 5 degree angle.
