Here are the answers to [[2021-2022 Honors Chem328 Polarity, IMF and Physical Properties Review HW]] 
 
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) 
*P1Cl5: 40ve-, P is central atom & 0LP, Trigonal bipyramidal (90,120), dsp3 hybridized
*B1F3: 24ve-, 3 single bonds, B is central atom with no LP, Trigonal planar, 120&deg;, sp2
*N2: 10ve-, 1 triple bond, no central atom, Linear (180&deg;), NA
*S1O2: 18ve-, 1 single, 1 double bond, S is central atom with 1 LP, Planar unknown bond angle (can't be more specific), sp2 
 
3) 
*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 
 
4) dsp3 hybridized 
 
5)No the compound can not exist because N has only s & p orbitals and you d orbitals to make the hybridization (dsp3). 
 
6)+-->, Arrow over the more electronegative atom (or whatever way you memorize the symbol). 
 
7) Ionic &#916;EN> or = 1.7 
polar bond is 1.7<&#916;EN> or = 0.8 
non-polar &#916;EN<0.8 
 
8) Assume polar prove non-polar 
 
9) Ionic compound/bond same strength as metals/metallic bonds (Highest IMF) 
Polar molecules containing H-O,H-N,H-F (IMF name is hydrogen bonding) 
Polar molecules that don't (IMF name is dipole-dipole interaction) 
Non-polar molecules (IMF is London Dispersion Forces, LDF) (Lowest IMF). 
 
 
10) Dipole-dipole (D - D) interaction 
 
11) Yes 
 
12) No, polar or non-polar is for covalent (sharing) bonds 
 
13) False 
 
14) NH3, has more Hydrogen bond (actually it is H2O1) 
 
15) Boiling is based on CF, London dispersion forces (LDF). Octane has a higher IMF since it a higher molar meaning more electrons so more Instantaneous dipoles. So since IMF is higher, it will take more energy (higher boiling point) so boiling first means lower boiling point (Hexane). 
 
16) H2O1 is a polar molecule and oil is a hydrocarbon (CxHy) a non-polar molecule. So H2O1 exerts coloumbic force (CF) while oil does not. So H2O1 molecules are interacting with other H2O1 molecule so they will "push oil molecules" around so they will be together.
