- Consider any one of the four identical hybrid orbitals in the 109.5° set. a. What fraction of the clay in this hybrid orbital was originally red (carne from the 2s orbital)? b. What fraction of the clay in this hybrid orbital was originally green (carne from a 2porbital)? c. Explain the name “ s(1/4)p(3/4) hybrid orbital” for each of the four orbitals. d. In fact, each of the four hybrid orbitals in the 109.5° set is called an sp3 -hybrid orbital.Explain the name “ sp3 -hybrid orbital.”arrow_forwardThe most stable MO of 1,3,5-hexatriene and the most stable MO of benzene Which compound is more stable?

- The pentadienyl radical, H2C“CH¬CH“CH¬CH2#, has its unpaired electron delocalized over three carbon atoms.(a) Use resonance forms to show which three carbon atoms bear the unpaired electron.(b) How many MOs are there in the molecular orbital picture of the pentadienyl radical?(c) How many nodes are there in the lowest-energy MO of the pentadienyl system? How many in the highest-energy MO?(d) Draw the MOs of the pentadienyl system in order of increasing energy.

In pyrrole:a. the N has sp hybridizationb. all alternatives are correctc. the N has sp2 hybridizationd. the pair of nonbonding electrons (lone) are in the 2p orbital and are part of the pi systemarrow_forward
- Let us construct the molecular orbital diagram of ethylene (in pieces). a. First, construct the MO diagram of linear carbene (CH2). Draw pictures of all 6 orbitals b. Now bend the carbene to a bond angle of about 120°. How does this change your MO diagram? Draw pictures of all 6 orbitals. c. Now bring two of these carbene molecules together to make ethylene. Draw pictures of all 12 orbitals.arrow_forwardHow many anti-bonding pi-type molecular orbitals does 1,3-butadiene contain?arrow_forward5.)
