Right, suffering from incipient Alzheimer’s, I had to “look up”  C-tetrachloride, to ensure it wasn’t, say tetrachloro ethane or even tetra — ethylene.  If they'd used the better IUPAC tetrachloromethane ....  Once I got that,  it’s easy, and any intro-physics student should be able to answer the questions because of the obvious symmetry.  


bc suffers, and prays he’s not off the deep end. 


p.s. If it were other than zero — it’d require some memory of bond lengths and effective charges, etc. so one may "psych the question".
