the carbon tetrachloridemolecule,
positioned symmetrically as corners in atetrahedralconfiguration
joined to a centralcarbonatom
by singlecovalent bonds. Because of
this symmetrical geometry, CCl4is
the same structure, making carbon tetrachloride ahalomethane.
As asolvent, it is well suited to
dissolving other non-polar compounds, fats and oils. It can also dissolveiodine.
It is somewhatvolatile, giving offvaporshaving
a smell characteristic of other chlorinated solvents, somewhat similar to thetetrachloroethylenesmell
reminiscent ofdry cleaners' shops.
Note F and Cl are both in group 17 and can replace each other. They have the
same general structure.
