Hydrogen Properties, Uses, & Facts Britannica

Other molecules and functional groups containing two hydrogen atoms, such as water and methylene (CH2), also have ortho- and para- forms (e.g. orthowater and parawater), but this is of little significance for their thermal properties. Their ortho:para ratios differ from that of dihydrogen. The ortho and para forms of water have recently been isolated. Para water was found to be 25% more reactive for a proton-transfer reaction.
