Indicate the electron pair geometry and the molecular geometry for each of the six compounds listed below by completing the folowing table Compound Electron Pair Geometry Molecular Geometry CO2 inear linear tetrahedral SO3 trigonal planar trigonal planar bent linear trigonal pyramidal trigonal planar SO2 trigonal planar bent CH4 tetrahedral tetrahedral PF3 tetrahedral tetrahedral SCl2 tetrahedral bent Incorrect. You have not identified the correct molecular geometry for PF3. The Lewis structure for PF3 is

Solution

CO2:

C forms 2 sigma bonds only (and pi bonds which we don’t consider in hybridisation)

Since there are no lone pairs, both electron pair geometry and Molecular geometry will be same

So,

electron pair geometry = linear

Molecular geometry = linear

SO3:

S forms 3 sigma bonds only (and pi bonds which we don’t consider in hybridisation)

Since there are no lone pairs, both electron pair geometry and Molecular geometry will be same

So,

electron pair geometry = trigonal planar

Molecular geometry = trigonal planar

SO2:

S forms 2 sigma bonds and has a lone pair

So,

electron pair geometry = trigonal planar

Molecular geometry = bent

CH4:

C forms 4 sigma bonds only (and pi bonds which we don’t consider in hybridisation)

Since there are no lone pairs, both electron pair geometry and Molecular geometry will be same

So,

electron pair geometry = tetrahedral

Molecular geometry = tetrahedral

PF3:

P forms 3 sigma bonds and has 1 lone pair

So,

electron pair geometry = tetrahedral

Molecular geometry = trigonal pyramidal

SCl2:

S forms 2 sigma bonds and has 2 lone pair

So,

electron pair geometry = tetrahedral

Molecular geometry = bent
