    sp3 hybridised Explanation:- Boron has three valence electrons, so it is supposed to make 3 bonds in a molecule with hybridization, sp2 as only s and two p orbitals are used in hybridization and last p orbitalis vacant. But diborane, B2​H6​ contains two electrons each, three centred bonds. Each Boron atom is in a link with four hydrogen atoms. This makes tetrahedral geometry.  Hence, each Boron atom is sp3 - hybridized.

    got this anand?

    sir im not getting it sir

    eduncle-logo-app

    in diborane each boron atom is linked with 4 hydrogen...so sp3 hybridised

    eduncle-logo-app

    check

    have i did it right, please explain me,

    eduncle-logo-app

    where im wrong please tell me, it is showing sp3 in book aslo

    eduncle-logo-app

    no anand....in diborane there is 3 centred 2 electron bond...so directly you can not divide b2h6 into 2 bh3 and find hybridization...here in structure you see four H bond so sp3

    ohhkk

    eduncle-logo-app

    see bonding in diborane

    eduncle-logo-app

    i got in case of b2h6

    eduncle-logo-app

    thanks
