Following 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, polar
Mark the following statements as true or false. A molecule with very polar bonds can be nonpolar. blank The electrons in a polar bond are found nearer to the more electronegative element. blank Fluorine is very polarizable. blank Covalent bonds are partially ionic because of polarizability of atoms. blank Kr and Sr2- are isoelectronic.
When drawing the Lewis structure of the HCC13 molecule, the structure should represent a total of 26 valence electrons. What is the best description of the complete Lewis structure of the molecule? Select one: AH atom should be in the center with single bonds to each Cl atom and a double bond to the C atom. A Cl atom should be in the center with a single bond to the C atom and a single bond to the H atom. AC atom should be in the center with a double bond to the H atom and double bonds to each Cl atom. AC atom should be in the center with single bonds to each Cl atom and a single bond to the H atom.
How is molecular shape determined using Valence Shell Electron Pair Repulsion (VSEPR) theory? A) Shape is determined by the repulsion of the electron pairs in the bonded atoms. B) Shape is determined by the repulsion of the neutrons in the bonded atoms C) Shape is determined by the repulsion of the protons in the bonded atoms D) None of the other selections are true
