In the table below, write the molecular and electronic geometry for each structure, and determine the polarity of the compound (polar or non-polar).  If a compound is ionic, write N/A in each of the boxes for molecular geometry, electronic geometry, and polarity for that substance.

 

 

  1. H2CO (C is the central atom)

 

 

 

  1. Li2S

 

 

 

  1. PCl3

 

 

 

  1. CaBr2

 

 

 

  1. N2O (nitrogen is the central atom)
