Interpretation:The bond polarization in
Concept Introduction: On the basis of bonding, all chemical compounds widely classified as ionic and covalent compounds. Ionic compounds are composed of cation and anion which are held together through electrostatic force of attraction. Covalent compounds are composed by equal sharing of electrons between bonded atoms. They can be further classified as polar and non-polar covalent compounds. The non-polar compounds have same electronegativity of bonded atoms whereas polar covalent are composed of those bonded atoms which have significant difference in their electronegativity.

- 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_forwardA neutral molecule is identified as a tetrafluoride, XF4, where X is an unknown atom. If the molocule has a dipole moment of 0.63 D, can you give some possibilities for the identity of X?arrow_forwardIn each of the following molecules, a central atom is surrounded by a total of three atoms or unshared electron pairs: SnCl2, BCl3, SO2.

- A molecule XF6 (having no lone pairs) has a dipole moment of zero. (X denotes an unidentified element.) When two atoms of fluorine have been taken away, you get the molecule XF4, which has dipole moment of 0.632 D. XF6XF4+2F Describe the molecular geometry for each molecule. What are some possibilities for X?arrow_forwardGive approximate values for the indicated bond angles. angles in SF6 angle in XeF2 angle inarrow_forwardWhat are the bond angles predicted by the VSEPR model about the carbon atom in the formate ion, HCO2? Considering that the bonds to this atom are not identical, would you expect the experimental values to agree precisely with the VSEPR values? How might they differ?arrow_forward
