Does B2 Have a Sigma Molecular Orbital?

[Karan Punjabi]

Guys I studied Molecular orbital theory based on wave mechanics in lower level as i don't know what is wave mechanics so i saw molecular orbital diagram of boron di atomic molecule in which there are two pi molecular orbitals so my first question was that there must be first a sigma molecular orbital then there should be a pi molecular orbital and when i searched on B2 molecule i didn't got its existence any where. So does it exist or not?

The ordering of σ and π orbitals is complicated. See https://en.wikibooks.org/wiki/Intro...tal_Theory#.C2.A0.C2.A02.4_Diatomic_molecules

Yeah i got it...thanks for this valuable info. But do B2 molecule exist?

You get to a high enough temperature, yes.
