- Which of the following bonds are polar: (a) P—O; (b) S—F; (c) Br—Br; (d) O—Cl? Which is the more electronegative atom in each polar bond?arrow_forwardMixing SbCl3 and GaCl3 in a 1:1 molar ratio using liquid sulfur dioxide as a solvent gives a solidionic compound with the empirical formula GaSbCl6. A controversy arose over whether this compoundis [SbCl2]+[GaCl4]− or [GaCl2]+[SbCl4]−.(a) Predict the molecular structure of the two anions from the two choices using VSEPR theory.(b) It is learned that the cation in the compound has a bent structure. Based on this fact, whichformulation is the correct one?arrow_forwardThe average bond enthalpies of the C¬F and C¬Cl bonds are 485 kJ/mol and 328 kJ/mol, respectively. (a) What is the maximum wavelength that a photon can possess and still have sufficient energy to break the C ¬ F and C ¬ Clbonds, respectively?arrow_forward
- Which of the following trends in lattice energy is dueto differences in ionic radii? (a) NaCl 7 RbBr 7 CsBr,(b) BaO 7 KF, (c) SrO 7 SrCl2.arrow_forwardThe atomic radius of an oxygen atom is 73 pm, and the ionic radius of the ion O2 is 140 pm. Explain the relative radii by estimating Zeff for each of these species.arrow_forwardSome chemical reactions proceed by the in it ial loss or transfer of an electron to a diatomic species. Which of the molecules N2, NO. O2, C2, F2, and CN would you expect to be stabil ized by (a) the addit ion of an electron to form AB-. (b) the removal of an electron to form AB+?arrow_forward
- . Calculate the lattice energy of Li₂O(S). (AH(sublimation) K(s) = 77 kJ/mole, and AHƒ (Li₂O(s)) = −361 kJ/mole)arrow_forwardCarbon naturally occurs in two forms: diamond and graphite. Why do these two forms have very different properties? The key difference is that diamonds have other elements bonded within their structure. The differences are explained by the number of covalent and ionic bonds within each substance. The differences are explained by the density: graphite is very high and diamond is much lower. The differences are explained by how the carbon atoms within each substance are covalently bonded together.arrow_forwardSelenium tetrafluoride is produced from a reaction of elemental Se with chlorine trifluoride according to the balanced chemical equation: 3 Se(g) + 4 CIF3(g) → 3 SEF4(g) + 2 Cl2(g) AHrxn = -1874 kJ Using AHrxn and the table of bond energies below, determine the bond energy of the Se-F bonds in SeF4. Note that all bonds in the reactants and products are single bonds. Bond Bond Energy (k.J/mol) CI-F 253 CI-CI 243 The units are kJ/mol. Do not include units in your answer. Scientific notation is optional. To write scientific notation in Canvas, type "e" to replace "x 10". For example, "1 x 1014" is written "1e+14" in Canvas.arrow_forward
- To explain why AHan for RbCl is different than that for KCI, the student investigates factors that affect AHoln and finds that ionic radius and lattice enthalpy (which can be defined as the AH associated with the separation of a solid crystal into gaseous ions) contribute to the process. The students consults references and collects the data shown in the table below. lonic Radius (pm) lon к' 138 Rb* 152 b. Using principles of atomic structure, explain why the Rb' ion is larger than the K' ionarrow_forwardThe halogens form a class of compounds called the interhalogens, in which halogen atoms covalently bond to each other. Write the Lewis structures for the interhalogens BrCl3 and ICl4−.arrow_forwardBecause they have a complete valence layer, high ionization energy and virtually zero electron affinity, it was long considered that noble gases would not form chemical compounds. However, in 1962, the reaction between xenon (5s25p6 valence layer) and platinum hexafluoride was successfully carried out and, since then, more new compounds of noble gases have been synthesized. Such compounds demonstrate that one cannot uncritically accept the octet rule, in which it is considered that, in a chemical bond, atoms tend to acquire stability by assuming the electronic configuration of noble gas. How many electrons are there in the last layer of the atom of this noble gas? a) 10 b) 14 c) 8 d) 12 e) 6arrow_forward
