Question
Construct a represation of trigonal bipramidal molecular geometry :
Is the electron domain geometry the same as the molecualr geometry ?
uSE A PERSIODIC TABLE AND SUGGEST A MOLECULE THAT WOULD ADOPT A TRIGONAL BIPRAMIDAL STRUCTURE ?
Is it possible for a molecule to have a trigonal bipramidal molecular geometry and be polar ? to have a trigonal bipramidal molecular geometry and be nonpolar ?
what is the molecular geometry if one of the bons is replaced by a lone paire of electrons? does this change the affect of bong angels ?
Explanation / Answer
A molecule can have a different shape when referring to its electron-domain geometry than when referring to its molecular geometry. For example, sulfur dioxide, SO2, electron-domain geometry is trigonal planar. This is because it has 3 electron domains - the 6 valence electrons for sulfur form 2 single bonds with 2 oxygen atoms and sulfur has one non-bonding lone pair. Also related to electron-domain geometry is the fact that the sulfur has sp2 hybridization, since its geometry is trigonal planar.
When referring to the molecular geometry for sulfur dioxide, the molecular geometry is bent. Note that the bent shape is related to the diffence in electronegativity between sulfur and oxygen Since the difference in polarity is greater than zero, SO2 is a polar molecule. The polarity influences the bond angle for the bent geometry. The lone pairs are not considered when determining molecular geometry, only the bonds with the atoms are considered.
