Which of the following statements is false concerning bonding? Elements with extremely different electronegativities tend to form ionic bonds with each other. In an N—O bond. electron density is greater near the O atom. An N—O bond is an example of a polar covalent band. In general, chemical bonds form to minimize energy. The bond in KBr is formed by sharing electrons.
The percent ionic character of a bond can be approximated by the formula 16+3.52 , where is the magnitude of the difference in the electronegativities of the atoms (see Fig. 3.18). Calculate the percent ionic character of HF, HCl, HBr, HI, and CsF, and compare the results with those in Table 3.7.

1.1 Define electronegativity and explain why electronegativity increases with atomic number within a period of the Periodic Table. 1.2 Describe the type of bonding that exists in F2 (g) molecule. How does this type of bonding differ from that found in the HF (g) molecule? 1.3 Define hydrogen bonding using examples. 1.4 PH3 and NH3 moleculea are the same shape but the molecules are non-polar and polar respectively. Explain why this is so. 1.5 Give an example of molecule that has a coordinate covalent bond. 1.6 Draw a Lewis structure for each of the following molecules of ions: a) HF3 b) CIO3-
One scale for electronegativity is based on the concept thatthe electronegativity of any atom is proportional to theionization energy of the atom minus its electron affinity:electronegativity = k1I - EA2, where k is a proportionalityconstant. (a) How does this definition explain why the electronegativityof F is greater than that of Cl, even though Clhas the greater electron affinity? (b) Why are both ionizationenergy and electron affinity relevant to the notion ofelectronegativity? (c) By using data in Chapter 7, determinethe value of k that would lead to an electronegativity of 4.0for F under this definition. (d) Use your result from part (c)to determine the electronegativities of Cl and O using thisscale. (e) Another scale for electronegativity defines electronegativityas the average of an atom’s first ionization energyand its electron affinity. Using this scale, calculate the electronegativitiesfor the halogens, and scale them so that fluorinehas an electronegativity of 4.0. On this…
Draw the attraction between a water molecule and a molecule of BrCl4F. Br is the central atom in an expanded octet - count your electrons carefully. First, draw one molecule and add the partial charges where needed - use the ΔEN to determine the types of bonds. Then, draw the second molecule so that the δ+ on one molecule lines up across from the δ- on the other. Since we can't draw the molecules here you will answer questions about the drawings that you made on the homework worksheet. BrCl4F has one __________ bond between the Br and F with ΔEN = ____________ , and four ________ bonds between the Br and Cl with a ΔEN = _________ . The central Br has 6 REDs and the molecule is symmetrical/asymmetrical (answer is ___________ ) making it a polar/nonpolar (answer is __________ ) molecule. The central Br has a ___________ charge and the F has a ________ charge. H2O has 2 ____________ bonds with a ΔEN = ___________ . H2O has 4 REDs and is symmetrical/asymmetrical (answer…
