Analyze the bonds of ccl4. what is the shape of the ccl4 molecule? is it symmetrical? does this mean that the ccl4 molecule is polar or nonpolar?

C-Cl bond is polar.

As Cl is more electronegative than C,  

Cl pulls the shared electrons towards its side making the C-Cl bond polar.

Polar meaning C gets a partial positive charge and Cl gets a partial negative charge. Thus C-Cl bond becomes polar.

CCl4 molecule is tetrahedral.

And its shape is symmetrical.

That means its similar on all corners or all planes and it can be cut into equal halves from any plane.

C-Cl bond is polar.But the C-Cl polairty gets cancelled out as its pulled equally from all sides.

Since the molecule is symmetrical CCl4 is non polar.  

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
