Step 1 (a) Ionic (b) Nonpolar covalent (c) Polar covalent (d) Polar covalent (e) Nonpolar covalent (f) Polar covalent Step 2 Are the bonds in each of the following substances ionic, nonpolar covalent, or polar covalent? The nature of a bond depends on the modulus of the difference of electronegativity (|ΔEN|) between the atoms that form it. 1) If |ΔEN|=0, the bond nonpolar covalent 2) If 0&amp;lt;|ΔEN|≤2, the bond is polar covalent. 3) If |ΔEN|&amp;gt;2, the bond is ionic. Step 3 a) K Cl =|ΔEN|=|EN(K)−EN(Cl)|=|0.8−3.0|=2.2 The bond is ionic. b) P4=|ΔEN|=|EN(P)−EN(P)|=|2.1−2.1|=0.0 The bond is nonpolar covalent. c) BF3=|ΔEN|=|EN(B)−EN(F)|=|2.0−4.0|=2.0 The bond is polar covalent. d) SO2=|ΔEN|=|EN(S)−EN(O)|=|2.5−3.5|=1.0 The bond is polar covalent. e) Br2=|ΔEN|=|EN(Br)−EN(Br)|=|2.8−2.8|=0.0 The bond is nonpolar covalent. f) NO2=|ΔEN|=|EN(N)−EN(O)|=|3.0−3.5|=0.5 The bond is polar covalent.
