- Follow the directions of Question 1 for (a) C22- (b) NFO (c) BrF4+ (d) NI3arrow_forwardExplain in terms of bonding theory why all atoms of H2CCCCH2 must lie in the same plane.arrow_forwardWhich of the following statements is(are) true? Correct the false statements. a.The molecules SeS3, SeS2, PCl5, TeCl4, ICl3, and XeCl2 all exhibit at least one bond angle, which is approximately 120. b.The bond angle in SO2 should be similar to the bond angle in CS2 or SCl2. c.Of the compounds CF4, KrF4, and SeF4, only SeF4 exhibits an overall dipole moment (is polar). d.Central atoms in a molecule adopt a geometry of the bonded atoms and lone pairs about the central atom in order to maximize electron repulsions.arrow_forward
- Which of the following statements is/are true? Correct the false statements. a. The molecules SeS3. SeS2, PCl5, TeCl4, ICl3, and XeCl2 all exhibit at least one bond angle which is approximately 120. b. The bond angle in SO2 should be similar to the bond angle in CS2 or SCI2. c. Of the compounds CF4, KrF4, and SeF4, only SeF4 exhibits an overall dipole moment (is polar). d. Central atoms in a molecule adopt a geometry of the bonded atoms and lone pairs about the central atom in order to maximize electron repulsions.arrow_forwardThe ions ClF2 and ClF2+ have both been observed. Use the VSEPR model to predict the FClF bond angle in each.arrow_forwardThe nitrogennitrogen bond distance in N2 is 109 pm. On the basis of bond orders, would you expect the bond distance in N2+ to be less than or greater than 109 pm? Answer the same question for N2.arrow_forward
