2) has nuclear spin isomers like diatomic hydrogen, but with different populations of the two forms because the deuterium nucleus (deuteron) is a boson with nuclear spin equal to one. [25] There are six possible nuclear spin wave functions which are ortho or symmetric to exchange of the two nuclei, and three which are para or antisymmetric. [25]
Carboxylic acids tend to have higher boiling points than water, because of their greater surface areas and their tendency to form stabilized dimers through hydrogen bonds. For boiling to occur, either the dimer bonds must be broken or the entire dimer arrangement must be vaporized, increasing the enthalpy of vaporization requirements significantly.

1,2,4,5-Cyclohexanetetrol (also named cyclohexane-1,2,4,5-tetrol, 1,2,4,5-tetrahydroxycyclohexane, or para-cyclohexanetetrol) is an organic compound whose molecule can be described as a cyclohexane with four hydroxyl (OH) groups substituted for hydrogen atoms on two non-adjacent pairs of adjacent carbon atoms. Its formula can be written C 6 H ...
The former has one water of crystallization but the latter does not. Another example is the pair of titanium(III) chlorides, [Ti(H 2 O) 6]Cl 3 and [Ti(H 2 O) 4 Cl 2]Cl(H 2 O) 2. The former is violet and the latter, with two molecules of water of crystallization, is green. [2]
Thus, for example, ethene would have no structural isomers under the first interpretation; but replacing two of the hydrogen atoms (1 H) by deuterium atoms (2 H) may yield any of two structural isotopomers (1,1-dideuteroethene and 1,2-dideuteroethene), if both carbon atoms are the same isotope.
In chemistry, a water cluster is a discrete hydrogen bonded assembly or cluster of molecules of water. [ 1 ] [ 2 ] Many such clusters have been predicted by theoretical models ( in silico ), and some have been detected experimentally in various contexts such as ice , bulk liquid water, in the gas phase , in dilute mixtures with non-polar ...
C 3 H 4 O is a chemical formula that represents each of several actual and hypothetical compounds that differ in structure, but each consist of three atoms of carbon, four of hydrogen, and one of oxygen. The following compounds are among them:
