Question

What are the Ortho and para forms of hydrogen?

Answer 1

Hydrogen molecule also have another different kind of isomer, based on the nuclear spin. As we know, in one hydrogen molecule there are two hydrogen atom and each atom has one proton and one electron. Electron revolves around the positive center, and itself also spin in an axis arising an angular momentum. As like the spin of electrons, the nuclei of hydrogen molecule also spin in its axis. Such spin can be in two ways, either both nuclei or proton (one from each atom) can spin in same direction, or opposite to each other. If both the nuclei spin in same direction then it is called Ortho Hydrogen and if they spin in opposite direction, it is called Para Hydrogen.
