Study the following sketch of a molecular orbital (MO) in a homonuclear diatomic molecule. This MO was formed by combining one 2s atomic orbital from each atom. The dark dots in this sketch are the nuclei. Now use the sketch to complete the table below. Write the symbol for this MO. Is this a bonding or antibonding MO? What is the energy of this MO, compared to the energy of a 2s orbital on one of the separate atoms? 0 O bonding O antibonding O higher O lower O the same not enough information to decide a 2 00 X J S

Draw a sketch of all of the MO’s made from the atomic valence orbitals for F2

Use the MO diagrams to calculate the bond order for Li2+ and Li2−

Consider the molecular orbital model of Toluene. In the ground state how many molecular orbitals are filled with electrons? O FIVE TWO O SEVEN Ⓒ THREE O FOUR ⒸSIX

In SeO2, Indicate which atoms in the species need what hybrid orbitals in order to explain the bonding in the molecule or ion.  Describe each of the bonds in the species: (There is a ___ bond between the ___ atom and the ___ atom formed by the overlap of a ____ orbital on the ____ atom and the ___ orbital on the ____ atom)

In the diagram below, label each molecular orbital (MO) for B2. boronA MO's boron B \sigma *2s 2p 2p . . 2s 2s 1s 1s

2) a) Consider the following molecule . Given what you have learned about hybridization theory, draw an image or images explaining the bonding situation in this molecule. I want you to draw out all of the orbitals, hybrid orbitals and how they overlap to form the bonds in the molecule. Indicate the % s or p character in the given atomic and hybrid orbitals. Which C-C bond or bonds are the longest? In a paragraph or so explain the image or images you just drew. b) Lastly, consider the molecule below. Indicate the Molecular formula, the molar mass, label the hybridization of each atom except for hydrogen, indicate any chiral centers with a *, which bond or bonds are the shortest, identify by name of each functional group with an arrow pointing to the group.

Categorize each molecule according to which hybrid orbitals are used by the central atom to form. Use the letters to match to the orbital type sp sp^3 SO²- A No Answers Chosen No Answers Chosen SiCl₂O B sp^2 BeF2 C OC12 No Answers Chosen D R
