Here is the answers to [[2022-2023 Chem328 Review HW for Polarity, IMF and Physical Properties including Solutions, Molarity]]. 
 
1a) Ionic&nbsp;&nbsp;&nbsp; 
1b) Polar&nbsp;&nbsp;&nbsp; 
1c) Non-polar&nbsp;&nbsp;&nbsp; 
1d) Polar &nbsp;&nbsp;&nbsp; 
1e) Ionic &nbsp;&nbsp;&nbsp; 
1f) Polar 
 
2) Using Molecular Polarity table:
*CCl4, &#916;EN =0.5, 4 non-polar bonds, Tetrahedral (sym), NA, non-polar molecule, LDF 
*<nowiki>BeCl</nowiki>2, &#916;EN =1.5, 2 polar bonds, Linear (sym), Yes, non-polar molecule, LDF
*CS2, &#916;EN=0.0, 2 non-polar bonds, Linear (sym), non-polar molecule, LDF
*NF3, &#916;EN=1.0, 3 polar bonds, Pyramidal (not sym), polar molecule, dipole-dipole 
 
 
3) Made mistake, no question/problem 
 
4)+-->, Arrow over the more electronegative atom (or whatever way you memorize the symbol). 
 
5) Ionic &#916;EN> or = 1.8 
polar bond is 1.8<&#916;EN> or >0.4 
non-polar &#916;EN<=0.8 
 
8) Assume polar prove non-polar
