      Why benzene show absorbance band at 254nm??

    Sir, how can we understand whether they are occupied or unoccupied

    • @TETRAHEDRONCHEMISTRYCLASSES
      @TETRAHEDRONCHEMISTRYCLASSES  5 ปีที่แล้ว +3

      See, in case of butadiene you have total 4 pi electrons (2 double bonds), and there are four Molecular orbitals formed, one atomic orbital like atomic orbital can occupy only 2 electrons, thus first MO will get 2 electrons and it is occupied, second orbital will also get 2 electrons thus it is also occupied, now for remaining two molecular orbitals you don't have electrons thus third and fourth Molecular orbitals are unoccupied.

    How we can determine the lowest energy and highest energy orbital..on what basis

    • @TETRAHEDRONCHEMISTRYCLASSES
      @TETRAHEDRONCHEMISTRYCLASSES  5 ปีที่แล้ว +2

      Basically it is quantum mechanical calculation, but without using calculations, count the number of nodes, higher the number of nodes higher is the energy....

    Sir, is this topic in GATE CSE syllabus also?

    • @TETRAHEDRONCHEMISTRYCLASSES
      @TETRAHEDRONCHEMISTRYCLASSES  5 ปีที่แล้ว +2

      Yes, it is a part of Pericyclic reaction and Pericyclic reactions are there in the syllabus. One more thing, also check my video on pi Molecular orbitals of Benzene, a question was there in June 2019 CSIR NET exam from pi molecular orbitals of Benzene.
