a) Draw the molecular orbital diagram for HF. Be sure to clearly label orbital symmetries and indicate which orbitals are occupied by electrons. b) Identify and sketch the spatial representation of the HOMO and LUMO for the HF molecule. c) Based on your MO diagram, briefly explain why HF adopts a zigzag structure.

Can you help me with parts d,e,and f for the compound (ch3)2cchco2h

Give detailed Solution with explanation needed..don't give Handwritten answer

2. In the molecular orbital (MO) scheme for frontier orbitals of benzene, answer the following: a) how many of the carbons in benzene are sp²/p hybridized? b) how many p-n electrons does this system have? c) how many T,7* MOs can be constructed from the carbon p-orbitals? d) labeling these yn (n= 1 to ....) increasing in energy, how many vertical nodes do the following MOs have ? Y2,43 ¥4,Y5 e) on the hexagonal skeleton to right, draw the molecular orbital for y3, or y4. Are these MOs bonding, non-bonding or antibonding? Clearly show/tell why. f) in benzene, what orbital(s) is/are the HOMO? yn = g) what is the (value of the) aromatic stabilization energy for benzene? h) is benzene more or less stable than 1,3,5-cyclohexatriene? more less i) in two words, what is the structure of benzene? the LUMO? yn = kJ/mol (circle one)
