Chemical Principles: The Quest for Insight
- A resident expert on electronegativity comes up to visit with you. He makes two claims (seen below) about electronegativity with relation to covalent bonding. Is the expert correct or can you refute him with your knowledge of electronegativity? (a) If a diatomic molecule is made up of atoms X and Y, which have different electronegativities, the molecule must be polar. (b) The farther two atoms are apart in a bond, the larger the dipole moment will be.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_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_forward
- The dipole moment of chlorine monofluoride, ClF(g), is 0.88D. The bond length of the molecule is 1.63 Å. (a) Which atomis expected to have the partial negative charge? (b) What is thecharge on that atom in units of e?arrow_forwardCombine two elements (cesium, berryllium, bromine, and flourine) from the following: ( K, Mg, Mn, N, O, Fe, Cu, H, S, Kr,C, Na, Br, Cl) to form 5 different molecules, including one oxy atomic moleculeand one diatomic molecule from the given elements(cesium, berryllium, bromine, and flourine), and determine the following: a) the electronegativity of the compound (show your calculation) b) Is the selected molecule polar, or not? What type of bond is formed based onwhat you learned? Is it a strong or weak bond?arrow_forwardPredict whether the bonds in the following compounds are ionic or covalent: (a) NaI (sodium iodide); (b) H 2O 2 (hydrogen peroxide).arrow_forward
- In addition to ammonia, nitrogen forms three other hy-drides: hydrazine (N₂H₄), diazene (N₂H₂), and tetrazene (N₄H₄).(a) Use Lewis structures to compare the strength, length, and or-der of nitrogen-nitrogen bonds in hydrazine, diazene, and N₂.(b) Tetrazene (atom sequence H₂NNNNH₂) decomposes above 0°C to hydrazine and nitrogen gas. Draw a Lewis structure fortetrazene, and calculate ΔH°ᵣₓₙ for this decomposition.arrow_forwardConsider the A2X4 molecule depicted here, where A and Xare elements. The A¬A bond length in this molecule is d1,and the four A¬X bond lengths are each d2. (a) In terms ofd1 and d2, how could you define the bonding atomic radii ofatoms A and X? (b) In terms of d1 and d2, what would you predictfor the X¬X bond length of an X2 molecule?arrow_forwardConsider the A2X4 molecule depicted here, where A and Xare elements. The A¬A bond length in this molecule is d1,and the four A¬X bond lengths are each d2. (a) In terms ofd1 and d2, how could you define the bonding atomic radii ofatoms A and X? (b) In terms of d1 and d2, what would you predictfor the X¬X bond length of an X2 molecule? [Section 7.3]arrow_forward
- (b) List some properties of Group 1 elements which indicate they are all metals. (c) What valence do all Group 1 elements exhibit in their compounds? (a) Write the names and symbols of the elements of Group 2.arrow_forward(c) Draw the orbital diagrams and Lewis symbols to depict the formation of Na* and CI ions from the atoms. Give the formula of the compound formed. (d) The predicted bond length for HF is 109 pm (the sum of the covalent radii of H, 37 pm and F. 72 pm), however the actual bond length for HF is shorter (92 pm). It was observed that the difference between predicted and actual bond lengths becomes smalleor going down the halogen group from HF to HI Describe these observationsarrow_forwardUse the periodic table to (i) predict electron configurations for the following species: Arsenic ion, As3– Magnesium ion, Mg2+ Vanadium(II) ion, V2+ (ii) Write the electron configurations of each species in the noble gas notation. (iii) Draw an orbital diagram to represent 1 c above. Draw the Lewis electron dot structures of the following chemical species. In each case you must say whether or not the central atom obeys the Octet Rule. CS2 and H2S CF4 and SiH4 NH2Cl CO32– and BF3 PCl5 ClF3, XeF2, Calculate the formal charge on the Sulphur atom in the Sulphate anion structure shown below(picture attatched) Give the electron-pair and molecular geometries for NF3 and XeF4.arrow_forward
