Here are answers to 2020 CP Review for Polarity, Geometry, and IMF Test
1) See class work
2) See class work
3) See class work
4) +--->, see your notes
5) ΔEN : 0.0 - 0.4 - non-polar bond;0.5 - 1.6 - polar bond; 1.7 and higher - Ionic bond
6) All atoms give off valence electrons (all have low EN ), Metallic bond consists of cations with "sea of free flowing ve- between them.
7) Assume polar, prove non-polar.
8) 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).
9) H2O1, C1O1, C1H4
10a) IC, Fe2O3
10b) Hydrochloric acid
10c) N2F6
