Carbon tetrachloride has four polar covalent bonds. It is a tetrahedral molecule, so the charges are symmetrical. The \(\delta+\) part of the molecule (the carbon atom) is locked away at the ...

They attempted to polymerize two monomers: a tetrahedral molecule with four primary amines (-NH 2) at its vertices (TAM) and a triangular molecule with aldehydes (-CHO) at its vertices (TFPT/TFPB). In ...

The general formula is AB 2 O 4. The oxygens form an fcc lattice. The A cations occupy tetrahedral holes, and the B cation occupy octahedral holes. It then follows that 1/8 of the tetrahedral holes ...
