In c, the electronegative N has a positive charge. The structure with a 1— formal charge on O is most likely, since O is the most electronegative atom in the ion. The formal charges are large, but match electronegativity. Negative formal charge of 1— on Se, a low electronegativity atom. Negative formal charge on N, the most electronegative atom. BBest resonance structure of the three.
Large formal charges, not very likely. SNO — : a has a 1— formal charge on S. None of the structures II or III are as good; they have unlikely charges by electronegativity arguments or large charges. Experimental measurements show that the nitrogen—nitrogen distance The third resonance structure, with greater overall magnitudes of formal charges, is the poorest representation.
SeCl4 requires 10 electrons around Se. The lone pair of electrons in an equatorial position of a trigonal bipyramid distorts the shape by bending the axial chlorines back. I3 — requires 10 electrons around the central I and is linear. PSCl3 is nearly tetrahedral. IF4 — has 12 electrons around I and has a square planar shape. PH2 — has a bent structure, with two lone pairs. TeF4 2— has 12 electrons around Te, with a square planar shape. N3 — is linear, with two double bonds in its best resonance structure.
SeOCl4 has a distorted trigonal bipyramidal shape with the extra repulsion of the double bond placing oxygen in an equatorial position. ICl2 — has 10 electrons around I and is linear. H3PO3 has a distorted tetrahedral shape. BH4 — is tetrahedral. POCl3 is a distorted tetrahedron. The Cl—P—Cl angle is compressed to IO4 — is tetrahedral, with significant double bonding; all bonds are equivalent.
IO OH 5 has the oxygens arranged octahedrally, with hydrogens on five of the six oxygens. SOCl2 is trigonal pyramidal, with one lone pair and some double bond character in the S—O bond. ClOF4 — is a square pyramid. The double bonded O and the lone pair occupy opposite positions. The F—Xe—F angle is nearly linear Formal charges favor double bond character in the Xe—O bonds. The O—Xe—O angle is narrowed to SOF6 is nearly octahedral around the S. ClO2 is an odd electron molecule, with a bent shape, partial double bond character, and an angle of NO2 is another odd electron molecule, bent, with partial double bond character and an angle of This is larger than the angle of ClO2 because there is only one odd electron on N, rather than the one pair and single electron of ClO2.
N2H4 has a trigonal pyramidal shape at each N, and a gauche conformation. There is one lone pair on each N. CS2, like CO2, is linear with double bonds. The structure of XeOF5 — is based on a pentagonal bipyramid, with a lone pair and the oxygen atom in axial positions. See K. Christe et al. AsH3 should have the smallest angle, since it has the largest central atom. This minimizes the bond pair—bond pair repulsions and allows a smaller angle.
Arsenic is also the least electronegative central atom, allowing the electrons to be drawn out farther and lowering the repulsions further. The sodium salt The N—O electronegativity difference should pull electrons away from N, reducing the bp-bp repulsion and the angle. In addition, the greater electronegativity of Cl holds the electrons closer and increases bp-bp repulsion.
N3 — is linear, with two double bonds. O3 is bent see solution to 3. Adding an electron to O3 decreases the angle, as the odd electron spends part of its time on the central O, making two positions for electron repulsion. The decrease in angle is small, however, with angles of Klein, K. Armbruster, M. Jansen, Chem. In the case of O SiH3 2, the very large increase in bond angle over O CH3 2 suggests that the size of the SiH3 group also has a significant effect on the bond angle.
Some contribution from this would reduce the bond angle. Gary L. Miessler, St. Olaf College Donald A. Tarr, St. Olaf College. Availability This title is out of print. Overview Order Overview.
