Concept explainers
Use the simulation (http://openstaxcollege.org/l/16MolecPolarity) to perform the following exercises for a two-atom molecule:
(a) Adjust the electronegativity value so the bond dipole is pointing toward B. Then determine what the electronegativity values must be to switch the dipole so that it points toward A.
(b) With a partial positive charge on A, turn on the electric field and describe what happens.
(c) With a small partial negative charge on A, turn on the electric field and describe what happens.
(d) Reset all, and then with a large partial negative charge on A, turn on the electric field and describe what happens.

- Is it polar or nonpolar?arrow_forwardFollowing is a molecule with polar bonds whose shape was obtained using the VSEPR theory. Specify the molecular shape of this molecule, and whether the molecule is polar or nonpolar. (Hint: In terms of polarity, see whether the dipoles in the molecule cancel or not. A molecule containing polar bonds can be nanpolar if the dipoles cancel each other. You can imagine the dipoles as ropes pulling on the central atom–If the pulls cancel each other, that is, the central atom cannot move, then the molecule is nonpolar. If on the other hand the opposite is true, then the molecule is polar.) O trigonal pyramidal shape, nonpolar O trigonal planar shape, nonpolar O tetrahedral shape, polar O trigonal pyramidal shape, polar O trigonal planar shape, polararrow_forwardWhich of the following has the lowest electronegativity? (a)Sodium (Na) (b)Carbon (C) (c) All of these have the exact same electronegativity. (d)Hydrogen (H) (e)Sulfur (S)arrow_forward
- in the molecule PCI3 given the phosphorus has the electronegativity of 2.1 and the chlorine has an electronegativity of three point no we can conclude that this molecule isarrow_forwardA 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_forwardWhy is salt, NaCl, relatively harmless even though the elements that compose it, sodium and chlorine, are toxic?arrow_forward
- Write an electron configuration for each element and the corresponding Lewis structure. Indicate which electrons in the electron configuration are included in the Lewis structure.(a) N(b) C(c) Cl(d) Ararrow_forwardDiscuss using an appropriate example whynitrogen never has more than 4 bonds.arrow_forwardUse this link: http://phet.colorado.edu/en/simulation/molecule-polarity to perform the following exercises for a two-atom molecule: Adjust the electronegativity value so the bond dipole is pointing toward B. Then determine what the electronegativity values must be to switch the dipole so that it points toward A. a. Nothing happens b. The electronegativity of the first (A) must be increased so that it's greater than the second (B) c. The electronegativity of the second (B) must be increased to be even greater than the first (A) d. The molecule must be rotated 180° so that the arrow will point to the second (B)arrow_forward
- Write Lewis dot symbols for the following atoms and ions. (a) I (b) I− (c) S (d) S2−arrow_forwardHow does the potential energy of the system change (increase/ decrease) as two oppositely charged species approach each other?arrow_forwardQuestion 13 (a) Show the 3D structure of BrF4*. (b) Give the VSEPR shape.. (c) Give the molecular shape. (d) Is this molecule polar? Explain.arrow_forward
