- 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_forwardExplain why (I3)+ is bent, but (I3) is linear.arrow_forwardWhat hybridization is required for central atoms exhibiting trigonal bipyramidal geometry? Octahedral geometry? Describe the bonding of PF5, SF4, SF6, and IF5, using the localized electron model.arrow_forward
- Explain why (a) XeF2 has a linear molecular structure and not a bent one. (b) ClF3 has a T-shaped structure and not a trigonal-planar one.arrow_forwardThe sulfamate ion, H2NSO3, can be thought of as having been formed from the amide ion, NH2, and sulphur trioxide, SO3. (a) What are the electron-pair and molecular geometries or the amide ion and or SO3? What are the hybridizations of the N and S atoms, respectively? (b) Sketch a structure for the sulfamate ion, and estimate the bond angles. (c) What changes in hybridization do you expect for N and S in the course of the reaction NH2 + SO3 H2NSO3? (d) Is SO3 the donor of an electron pair or the acceptor of an electron pair in the reaction with amide ion? Does the electrostatic potential map shown below confirm your prediction?arrow_forwardSketch the resonance structures for the nitrate ion, NO3. Is the hybridization of the N atom the same or different in each structure? Describe the orbitals involved in bond formation by the central N atom.arrow_forward
- In the ammonia (NH3) molecule, three hydrogen (H) atoms form an equilateral triangle, with the center of the triangle at distance d = 94.0 pm (picometer) from each hydrogen atom. The nitrogen (N) atom is at the apex of a pyramid, with the three hydrogen atoms forming the base. The nitrogen-to-hydrogen atomic mass ratio is 13.9, and the nitrogen-to-hydrogen distance is L = 101.4pm. What are the (a)x and (b)y coordinates of the molecule's center of mass? [Answer: (a) 0; (b)31.3 pm]. SHOW work, work needs to be shown!arrow_forward16. For the molecule BrF5, what is its molecular geometry? Group of answer choices A. Square pyramid B. Octahedral C. trigonal pyramid D. tetrahedralarrow_forwardGive the number of protons and electrons in a. An N2 molecule b. An N3- unit c. An N5+ unit d. An N5N5 saltarrow_forward
- Predict the structure that TlCl would adopt if itis known that the cation radius for Tl+is159 pm and the anion radius for Clis 181 pmarrow_forward1a)Identify the molecules below that contains 2-sigma bonding orbitals and 2-pi bonding orbitals? why? a. ethane b. methanol c.ethene d. carbon dioxide 1b) What of the following polyatomic ions contains the fewest valence electrons? why? a. Chlorate b. Chlorite c. hypochlorite d. bicrabonatearrow_forwardOne of the “grand challenges” for engineering recently identified by the U.S. National Academy of Engineering is the capture of carbon dioxide produced by the burning of fossil fuels. Although carbon and oxygen have significantly different electronegativities, CO2 cannot easily be separated from air by applying a voltage in the smokestack of the power plant where it is generated. How does the geometry of carbon dioxide account for this observation?arrow_forward
