Double bonds may be conjugated, meaning that there is one single bond between them. Identify all the atoms in the structure below that must lie in the same plane. ***

Draw the simplest set of curved arrows that shows how the structure on the left could be turned into the structure on the right. Show all lone pairs. If you need to expand part of the structure to show some lone pairs, expand it by drawing in all atoms and bond lines. Br Br to

Describe the AXE labeling system for VSEPR in detail.  What does each letter stand for? For each of the electron and molecular geometries, assign the AXE notation.

Which of the following properties would you predict that the molecule C7H16 would have based on its structure shown here?

Predict the splitting pattern of Ha in the structure. На CH-CH3 H3C CH2CH-CH3 H, will be split into a sextet. O None of the other choices. O H, will be split into an octet. O H, will be split into a septet. O H, will be split into a pentet.

Consider three molecules: heptane, trans-3-heptene, and cis-3-heptene. Compare the effect a cis bond has on the overall shape of a 3-heptene molecule to the effect a trans bond has.

D a Given that the spatial requirement of a lone pair is greater than that of a bond pair, explain why XeF2 has a linear molecular structure and not a bent one. The four lone pairs of XeF2 occupy the equatorial positions. The angles between lone pairs are 60°, so there is less lone pair/lone pair repulsion with this arrangement. O The two lone pairs of XeF2 occupy the equatorial positions. The angle between lone pairs is 180°, so there is less lone pair/lone pair repulsion with this arrangement. O The two lone pairs of XeF2 occupy the equatorial positions. The angle between lone pairs is 60°, so there is less lone pair/lone pair repulsion with this arrangement. O The three lone pairs of XeF2 occupy the equatorial positions. The angles between lone pairs are 120°, so there is less lone pair/lone pair repulsion with this arrangement. Submit
