- There are several molecular structures based on the trigonal bipyramid geometry (see Table 8.9). Three such structures are Which of the compounds in Exercises 91 and 92 have these molecular structures? PF5, SF4, ClF3 and Br3 SF6, ClF5, and XeF4arrow_forwardAn important starting material for the manufacture ofpolyphosphazenes is the cyclic molecule (NPCl₂)₃. The mol-ecule has a symmetrical six-membered ring of alternating N and P atoms, with the Cl atoms bonded to the P atoms. The nitrogen-phosphorus bond length is significantly less than that expectedfor an N−P single bond.(a) Draw a likely Lewis structure for the molecule.(b) How many lone pairs of electrons do the ring atoms have?(c) What is the order of the nitrogen-phosphorus bond?arrow_forwardLight of appropriate wavelength can break chemical bonds. Light having λ < 240 nm can dissociate gaseous O2. It requires light with λ < 819 nm to dissociate gaseous H2O2 to 2 OH. Assume that all of the photon energy is used solely for these dissociations. (a) Calculate the energy required to dissociate (i) O2 and (ii) H2O2. (b) Consider the results of part (a). How well do they correlate with the Lewis structures of O2 and H2O2? Explain your answer.arrow_forward
- A variety of chlorine oxide fluorides and related cations and anions are known. They tend to be powerful oxidizing and fluorinating agents. FClO3 is the most stable of this group of compounds and has been studied as an oxidizing component in rocket propellants. Draw a Lewis structure for F3ClO, F2ClO2+, and F3ClO2. What is the molecular structure for each species, and what is the expected hybridization of the central chlorine atom in each compound or ion?arrow_forwarda Carbonyl fluoride, COF2, is an extremely poisonous gas used in organofluorine synthesis. Give the valence bond description of the carbonyl fluoride molecule. (Both fluorine atoms are attached to the carbon atom.) b Nitrogen, N2, makes up about 80% of the earths atmosphere. Give the valence bond description of this molecule.arrow_forwardPredict die molecular structure and bond angles for each molecule or ion in Exercises 88 and 94. a. POCl3, SO42, XeO4, PO43, ClO4 b. NF3, SO32, PO33, ClO3 c.ClO2, SCl2, PCl2 d. Considering your answers to parts a, b, and c. what conclusions can you draw concerning the structures of species containing the same number of atoms and the same number of valence electrons? (O3), sulfur dioxide, and sulfur trioxide.arrow_forward
- Write Lewis structures and predict the molecular structures of the following. (See Exercises 25 and 26.) a. OCl2, KrF2, BeH2, SO2 b. SO3, NF3, TF3 c. CF4 SeF4, KrF4 d. IF5, AsF5 Which of these compounds are polar?arrow_forwardThe formula for nitryl chloride is ClNO2 (in which N is the central atom). (a) Draw the Lewis structure for the molecule, including all resonance structures. (b) What is the NO bond order? (c) Describe the electron-pair and molecular geometries, and give values for all bond angles. (d) What is the most polar bond in the molecule? Is the molecule polar? (e) The computer program used to calculate electrostatic potential surfaces gave the following charges on atoms in the molecule: A = 0.03, B = 0.26, and C = +0.56. Identify the atoms A, B, and C. Are these calculated charges in accord with your predictions?arrow_forwardExplain in terms of bonding theory why all atoms of H2CCCCH2 must lie in the same plane.arrow_forward
- Predict the molecular structure (including bond angles) for each of the following. (See Exercises 115 and 116.) a. XeCl2 b. ICl3 c. TeF4 d. PCl5arrow_forwardWhich of the following statements is/are true? Correct the false statements. a. It is impossible to satisfy the octet rule for all atoms in XeF2. b. Because SF4 exists, OF4 should also exist, because oxygen is in the same family as sulfur. c. The bond in No+ should be stronger than the bond in No. d. As predicted from the two Lewis structures for ozone, one oxygen-oxygen bond is stronger than the other oxygen-oxygen bond.arrow_forward
