Interpretation:
The cations
Concept Introduction:
In any polar covalent bond, the difference in electronegativities gives rise to partial positive and negative charges respectively on the cation and anions.
The covalent character is determined with respect to the relative extent of distortion of anionic cloud of anion. For instance, highly charged small alkali metal cation such as
In general, greater is the charge on the alkali metal cation or smaller is the size of cation more is its polarizing power to distort the electron cloud of anion. Likewise greater is the polarizability of anion more easily its electron cloud is distorted by a cation.

Chemical Principles: The Quest for Insight
- In the gas phase, positive and negative ions form ion pairs that are like molecules. An example is KF, which is found to have a dipole moment of 28.7 1030 C m and a distance of separation between the two ions of 217.2 pm. Use this information and the definition of dipole moment to calculate the partial charge on each atom. Compare your result with the expected charge, which is the charge on an electron, 1.602 1019 C. Based on your result, is KF really completely ionic?arrow_forwardFrom the electron-pair repulsion model, predict the geometry of the following molecules: a TeF6 b ClF5 c SeF4 d SbF5arrow_forwardIn the molecular orbital mode l, compare and contrast bonds with bonds. What orbitals form the bonds and what orbitals form the bonds? Assume the z-axis is the internuclear axis.arrow_forward
- Consider the following molecules: SiH4, PH3, H2S. In each case, a central atom is surrounded by four electron pairs. In which of these molecules would you expect the bond angle to be less than 109.5? Explain your reasoning.arrow_forwardCalcium cyanamide, CaNCN, is used both to kill weeds and as a fertilizer. Give the Lewis structure of the NCN2 ion and the bonded-atom lone-pair arrangement and hybridization of the carbon atom.arrow_forwardYou hear a student from a nearby group say that “Electron domains repel one another.” Citeevidence from Figure 1.2 to support or refute this statement.arrow_forward
- If you have three electron regions around a central atom, how can you have a triangular planar molecule? An angular molecule? What bond angles are predicted in each case?arrow_forwardConsider the molecules AlCl3 (aluminum chloride) and CF4 (carbon tetrafluoride). a. Draw the valence shell representation of each. b. Predict the value of the XYX bond angle, and explain your reasoning.arrow_forwardIdentify the orbitals on each of the atoms that form the bonds in H3CCN. How many bonds and bonds form?arrow_forward
- Indicate which molecules are polar and which are nonpolar. (a) SeO2 (b) N2O (N is the central atom) (c) SCl4arrow_forwardis this polar or non polar?arrow_forwardExplain whether the following molecules are either polar or non-polar: AlCl3, CH4, HCN, H2O, NH3.
