No, PF5 is not a dipole-dipole molecule. It has a trigonal bipyramidal geometry with fluorine atoms arranged symmetrically around the central phosphorus atom, resulting in a nonpolar molecule.

Which of pf5 or sf6 does not have symmetrical geometry and why?

SF6 does not have symmetrical geometry, while PF5 does. This is because SF6 has a trigonal bipyramidal molecular geometry, with six bonding pairs and no lone pairs, leading to an overall asymmetrical shape. In contrast, PF5 has a trigonal bipyramidal molecular geometry with five bonding pairs and one lone pair, resulting in a symmetrical shape due to the lone pair occupying one of the equatorial positions.


What does PF5 stand for in chemistry?

Iit is phosphorus penta fluoride a molecule with Trigonal bipyramidal geometry.


What is the molecular geometry of PF5?

3 bonding pairs between P and 3x F atoms.1 free pair at central P atom.3 free pairs on each of the F atoms.Cf in 'Related links' below this answer page


Which compounds occur octet expansion?

Any element with an atomic number greater than 10 is capable of hypervalency. Electrons in the valence shell of these elements can be placed into hybridized d-orbitals during bonding if it is necessary to reduce the formal charge on the central atom of a molecule. Examples include PF5, SF6, AsF5, and XeF4.


How many atoms does the phosphorus atom connect to?

Phosphorus has two valencies 3 and 5. 3 - in compounds such as PH3, PCl3, P4O6 5 - PCl5, P4O10 In terms of cordination, the "count" of all the atoms around a P atom it can have 2- 9 atoms around it. Examples are below:- 2 - in OPCH2 3 - in PH3 4 - in PO43- 5 - in PF5 6 - in PF6- And in some phosphides where there bond is more ionic even higher coordination numbers are known:- 7 - in crystals of Ta2P 8 - in crystals of Hf2P 9 - Ti3P
