The molecule CIF, belongs to the C4, point group. Use the character table below to answer the following questions.

Example: If this question were asking about the composition of the MOs of water (C₂, point group), your answer would include the following: a₁: 2s (oxygen), H₂ SALC, and 2pz (oxygen) e) Which molecular orbital do you predict to be the most bonding? Draw a picture of this orbital including the phase. f) d-orbitals are not important for the bonding description of CIF5. Give a brief reason why.
