- Two variations of the octahedral geometry (see Table 4-1) are illustrated below. Which of the compounds/ions Br3, ClF3, XeF4, SF4, PF5, ClF5, and SF6 have these molecular structures?arrow_forwardCompare Figs. 4-47 and 4-49. Why are they different? Because B2 is known to be paramagnetic, the 2p and 2p molecular orbitals must be switched from the first prediction. What is the rationale for this? Why might one expect the 2p to be lower in energy than the 2p? Why cant we use diatomic oxygen to help us decide whether the 2p, or 2p, is lower in energy?arrow_forwardExplain in terms of bonding theory why all four hydrogen atoms of allene, H2CCCH2, cannot lie in the same plane.arrow_forward
- Why do we hybtidize atomic orbitals to explain the bonding in covalent compounds? What type of bonds form from hybrid orbitals: sigma or pi? Explain.arrow_forwardWhat modification to the molecular orbital model was made from the experimental evidence that B2 is paramagnetic?arrow_forwardAcrylonitrile, C3H3N is the building mer Orlon. Its Lewis structure is What is the hybridization of nitrogen and of the three numbered carbon atoms?arrow_forward
- Which linear combination of H and F atomic orbitals, f;, forms the bonding molecular orbital, y, in HF? Notes: The coefficient, c, represents the fractional contribution of f to y. Assume the z axis is the internuclear axis. y = -CHỘHIS – CPOFIS, CH CP y = CHYHIS + CrOF2pr, has cH = CH y = CHVHIS - CrOF2px, has CH < CF y = CHOHIS + CrộF2pz, has CH < CFarrow_forwardOne of the molecular orbitals of the H2- ion is sketched below: (a) Is the molecular orbital a σ or π MO? Is it bonding orantibonding? (b) In H2-, how many electrons occupy theMO shown above? (c) What is the bond order in the H2-ion? (d) Compared to the H—H bond in H2, the H—Hbond in H2- is expected to be which of the following:(i) Shorter and stronger, (ii) longer and stronger, (iii) shorterand weaker, (iv) longer and weaker, or (v) the same lengthand strength?arrow_forward(a) Complete the Lewis structure for the molecule shown below. How many lone pairs are there? H-C H 1 H (b) Give the hybridizations of the following atoms in the structure: (i) Ca; (ii) Ob (c) Give approximate values of the following bond angles: (i) O a-Ca-Ob; (ii) С a -О b-Сbarrow_forward

(a) Based on the numberof electrons, can you determine the identity of X? (b) Wouldthe molecule be diamagnetic or paramagnetic? (c) Considerthe p2p MOs of the molecule. Would you expect them to havea greater atomic orbital contribution from C, have a greateratomic orbital contribution from X, or be an equal mixtureof atomic orbitals from the two atoms?arrow_forwardс ☐ng.cengage.com/static/nb/ui/evo/index.html?deploymentid=5735112480241329813180832311&elSBN=9781305862883&id=1707785992&snapshoti...
