ake the four hydrogen 1s orbitals of CH4 and determine how they transform under Td. b) Confirm that it is possible to reduce this representation to A1 + T2. c) With which atomic orbitals on C would it be possible to form MOs with H1s SALCs of symmetry A1 + T2

H-He-H2+ is a linear trinuclear with He occupying the central position and the two hydrogen occupying the terminal positions. Build a reasonable qualitative molecular orbital diagram

What are the symmetry elements of the following molecules?

On one-electron oxidation of a five valence electron AH₂ compound (C₂, point group) to a closed shell (no unpaired electrons) four valence electron C₂, cationic species, what is the symmetry of the highest energy occupied molecular orbital, and what happens to the energy of this orbital when the four valence electron AH2 C2y cation changes to a Doch geometry? O 2a₁ and stabilised (decreases in energy) O 2a₁ and destabilised (increases in energy) O 1b2 and stabilised (decreases in energy) O b₁ and no change in energy
