Hi. I need help figuring this out. I am lost. Thanks.
For the molecule, CBr4, determine the following:
Name- Carbon Tetrabromide
Polarity of bonds (draw dipoles)-?
Polarity of molecules-?
Type of intermolecular forces-?
Carbon tetrabromide is the trivial name. The IUPAC name is tetrabromomethane.
These structures are almost impossible to draw on the boards because of a spacing problem. I assume you know how to draw them. If you don't let me know and I can tell you how to do it.
The above is about the best I can do. Now add 6 electrons around each Br (left, right, top or bottom unless I have already drawn a pair there).
Here is a site on the web that may help you visualize it.
polarity of bonds. Draw arrows from Br to C with +end on C end and arrow end (>) on the Br.
The molecule as a whole has no net dipole although each C-Br bond is a polar bond. It has no net dipole because it is symmetrical in space, shaped like a tetrahedron.
