Please select the molecule(s) that 1) its molecular shape is different from its electron group shape, and/or 2) the central bonds are not identical. NH3 BF3 PF5 PF3 SF4 ICl3 BrF5 XeF2 XeF4 SF6  ClO2- SO42- NO2+ PO43- NO3-

Arrange the compounds below in decreasing order of the lonic character of the bonds in them. That is, pick I for the compound with the most lonic bonds, pick 2 for the compound with the next most ionic bonds, and so on. ionic character compound of bonds RbCI (Choose one) CSCI (Choose one) PCI, (Choose one) SICI, (Choose one) I (most ionic) 4 (least ionic)

O Electronic Structure and Chemical Bonding Predicting bond polarity 0/5 C In each of the molecules drawn below one chemical bond is colored red. Decide whether this bond is likely to be polar or not. If the bond is likely to be polar, write down the chemical symbol for the atom which will have more negative charge. H-CC-H O The highlighted bond is polar and the more negative atom is ☐ O The highlighted bond is nonpolar. :NEN: O The highlighted bond is polar and the more negative atom is O The highlighted bond is nonpolar. H H-N-H O The highlighted bond is polar and the more negative atom is ☐ The highlighted bond is nonpolar. G
