Question

1.      The polarity of a molecule depends on the polarity of the bonds within the molecules as well as the shape of the molecule. All of the following statements are true concerning the polarity of a molecule EXCEPT

A. polar molecules have   three-dimensional shapes while nonpolar molecules are two-dimensional or   flat.

B. molecules with symmetrically   arranged polar bonds to the same element are nonpolar because the individual   bond dipoles cancel out.

C. linear molecules formed from   only two atoms are nonpolar if they are formed from two atoms of the same   element.

D. linear molecules formed from   only two atoms are polar if they are formed from two atoms of different   elements with a difference in electronegativity.

E. molecules with symmetrically   arranged polar bonds to different elements are polar as long as the   individual bond dipoles do not cancel out.

  

A. polar molecules have   three-dimensional shapes while nonpolar molecules are two-dimensional or   flat.

     

B. molecules with symmetrically   arranged polar bonds to the same element are nonpolar because the individual   bond dipoles cancel out.

     

C. linear molecules formed from   only two atoms are nonpolar if they are formed from two atoms of the same   element.

     

D. linear molecules formed from   only two atoms are polar if they are formed from two atoms of different   elements with a difference in electronegativity.

     

E. molecules with symmetrically   arranged polar bonds to different elements are polar as long as the   individual bond dipoles do not cancel out.

  

Explanation / Answer

B. molecules with symmetrically arranged polar bonds to the same element are nonpolar because the individual bond dipoles cancel out.
