- If an element is bonded to 4 other atoms and has a formal charge of +1, what group must the element be in? I know that group 3A atoms are elctron deficient, and that period 3 elements and below, except for group 3A elements like Aluminum, can expand their octet because of their available d-orbital, which may not be relevant to this problem. I don't understand this question, or why the answer would be 5A. Is it because 5A have odd valence electrons, and can form free radicals, like NO?arrow_forwardIs the electron density consistentwith equal contributions from the tworesonance structures for O3? Explain.arrow_forwardThe percent ionic character of the bonds in several interhalogen Molecules (as estimated from their measured dipole moments and bond lengths) are ClF (11%), BrF(15%), BrCl (5.6%), ICl(5.8%), and IBr (10%). Estimate the percent ionic characters for each of these molecules, using the equation in Problem 37, and compare them with the given values.arrow_forward
- The diatomic molecule OH exists in the gas phase. The bond length and bond energy have been measured to be 97.06 pm and 424.7 kJ/mol, respectively. Assume that the OH molecule is analogous to the HF molecule discussed in the chapter and that molecular orbitals result from the overlap of a lowerenergy pz, orbital from oxygen with the higher-energy ls orbital of hydrogen (the OH bond lies along the z-axis). a. Which of the two molecular orbitals will have the greater hydrogen 1s character? b. Can the 2px orbital of oxygen form molecular orbitals with the 1s orbital of hydrogen? Explain. c. Knowing that only the 2p orbitals of oxygen will interact significantly with the 1s orbital of hydrogen, complete the molecular orbital energy-level diagram for OH. Place the correct number of electrons in the energy levels. d. Estimate the bond order for OH. e. Predict whether the bond order of OH+ will be greater than, less than, or the same as that of OH. Explain.arrow_forwardThe transport of O2 in the blood is carried out by hemoglobin. Carbon monoxide (CO) can interfere with O2 transport because hemoglobin has a stronger affinity for CO than for O2. If CO is present, normal uptake of O2 is prevented, depriving the body of needed O2. Using the molecular orbital model, write the electron configurations for CO and for O2. From your configurations, give two property differences between CO and O2.arrow_forwardGive the Lewis structure, molecular structure, and hybridization of the oxygen atom for OF2. Would you expect OF2 to be a strong oxidizing agent like O2F2 discussed in Exercise 61?arrow_forward
- Although nitrogen trifluoride (NF3) is a thermally stable compound, nitrogen triiodide (Nl3) is known to be a highly explosive material. NI3 can be synthesized according to the equation BN(s)+3IF(g)BF3(g)+NI3(g) a. What is the enthalpy of formation for NI3(s) given the enthalpy of reaction ( 307 kJ) and the enthalpies of formation for BN(s) (254 kJ/mol), IF(g) ( 96 kJ/mol), and BF3(g) ( 1136 kJ/mol)? b. It is reported that when the synthesis of NI3 is conducted using 4 moles of IF for every l mole of BN. one of the by-products isolated is [IF2]+ [BF4]. What are the molecular geometries of the species in this by-product? What are the hybridizations of the central atoms in each species in the by-product?arrow_forwardHigh-resolution photoelectron spectroscopy has provided information on the energy levels and bond distance in the ion. Prepare a molecular orbital energy level diagram for this ion Ar2+. How would you expect the bond distance in to compare with 198.8 pm, the bond distance in Cl2arrow_forwardThe sulfate ion can be represented with four S-O bonds or with two S-O and two So=O bonds.(a) Which representation is better from the standpoint of formal charges?(b) What is the shape of the sulfate ion, and what hybrid orbitals of S are postulated for the σ bonding?(c) In view of the answer to part (b), what orbitals of S must be used for the π bonds? What orbitals of O?(d) Draw a diagram to show how one atomic orbital from S and one from O overlap to form a π bond.arrow_forward
