chemical bonding Flashcards
molecular orbitals are polycentric/monocenric
polycentric
soem properties of molecular orbital
only atomic orbitals of same energy combine to form molecular orbitals,the electrons occupy molecular orbitals,obeys hunds aufbau and pauli
wahtis molecular orbital
the probability of finding electron in molecule is highest in molecular orbital
how are mo fromed
combination f atomic orbitals
repulsion of nucleus is less in which mo
bonding mo therfore energy is less and electron repulsion on abmo is high energy increases
what happens to the toala energy when mo id fromed
the energy of molecular orbitals is same as when is was atomic
can 2px and 2py combine because they have same energy
no even though they have same energy their symmetry is diferent
electron density mut be maximum in mo
treu
which bond is symmetric
sigma
why are pi bonds unsymmetric
because they have +ve and -ve lobes above and below the bond axis
what is the differnec in B2 AND O2
the 2pz orbital has more energy than the pi orbitals for B2
