1a) Ionic 1b) Polar 1c) Non-polar 1d) Polar 1e) Ionic 1f) Polar

2)

N₁H₃: 8ve^-, 3 single bonds, N is central atom with 1 lone pair (LP), Pyramidal (107.0^o), sp³
Si₁H₄,
F₂: 14ve^-, 1 single bond, no central atom, Linear (180^o), NA

CCl₄, ΔEN =0.5, 4 non-polar bonds, Tetrahedral (sym), NA, non-polar molecule, LDF
BeCl₂, Δ EN =1.5, 2 polar bonds, Linear (sym), Yes, non-polar molecule, LDF
C₁O₁, Δ EN=0.0, 2 non-polar bonds, Linear (sym), non-polar molecule, LDF
NF₃, Δ EN=1.0, 3 polar bonds, Pyramidal (not sym), polar molecule, dipole-dipole

4) Information on both reactants

5) Vapor (if it is a gas at room temperature sis called a gas)

6) Liquid particles need to obtain enough energy to overcome its IMF and go into the gas phase.

7) Evaporation occurs a) on the surface of the liquid (boiling occurs in the bulk of the liquid) and b) at any temperature up to but not including the boiling point.

8) Will discuss

9) Ionic cpd ) )ΔEN > and = to 1.7
Polar 1.7>ΔEN> and = 0.8
Non-polar ΔEN < 0.8
