    yes simun what's your doubt?

    eduncle-logo-app

    sir what is banana bond and bridge and terminal bond here

    eduncle-logo-app

    yes wait...

    eduncle-logo-app

    see simun

    eduncle-logo-app

    Boron 3 valence electron hote hai so wo 2 electrons se 2 terminal H ke sath bond bna liye hai to boron ke pass 1 VE bach rha hai...so 3 center 2 electron bond bante hai jise banana bond khte hai

    eduncle-logo-app

    electron 2 or centre 3

    ye dono bond kese ban rahe hein sir

    eduncle-logo-app

    wo actual bond nhi hai simun

    eduncle-logo-app

    It is just like oscillating

    eduncle-logo-app

    actual 2 electron se bane hai or 3 centre ke sath...

    Simun did you get this??

    eduncle-logo-app

    sir back bonding I bare mein kon se chapter mein dia hoga

    eduncle-logo-app

    yes you do study here

    sir potential energy of banana bond is less then that of terminal bond why ?

    eduncle-logo-app

    the bond order of B-H bonds is 1, whereas the bond order of the banana bond is divided by 2, thus 0.5. Bond order is used to determine the strength of bonds: the smaller the bond order, the weaker the bond. Hence, the bridge bonds are weaker than the terminal bonds.

    eduncle-logo-app

    Strong bonds have low potential energy and weak bonds have high potential energy.
