Question

Please Show all work and explain. also please explain the differecne between EDG and molecular geometry, which do you include the electrons?

21. What are the electron domain geometry (EDG) and the polarity of these two molecules? KrFs SO Polar or Polar or EDG nonpolar? EDG nonpolar? A. linear Tetrahedral polar nonpolar B. Trigonal bipyramid polar Trigonal planar nonpolar C. linear nonpolar Trigonal planar polar D. bent Trigonal planar nonpolar polar E. Trigonal bipyramid nonpolar Trigonal planar nonpolar 22. Put these in order of increasing vapor pressure at room temperature. Cl

Explanation / Answer

in KrF2 central atom Kr involve in sp3d hybridisation.But in KrF2 central atom Kr contains three lone pair of electrons ans two bond pair of electrons.The electr on domaine geometry is trigonal bipyramidal.The molecular geometry of KrF2 is linear.So it is polar molecule.

in So3 central atom S involve in SP2 hybridisation .No lone pair of eltrons on central atoms .The electron geometry is planar trigonal. The molecular geometry is planar trigonal. So it non polar molecule.

B trigonal bipyramidal    polar                   trigonal planar   non polar
