Question

Are the bonds in each of the following substances ionic, nonpolar covalent, or polar covalent? (a) KCI (b) P4 O ionic ionic nonpolar covalent O polar covalent nonpolar covalent O polar covalent (c) BF3 (d) SO2 O ionic O nonpolar covalent O polar covalent O ionic O nonpolar covalent O polar covalent (e) Br2 (f) NO2 O ionic O nonpolar covalent O polar covalent O ionic nonpolar covalent O polar covalent Arrange the substances with polar covalent bonds in order of increasing bond polarity. O KCI O P4 O SO2 O SO2 ara O Br2 KCI 4 SO Br2 O NO2 NO2 O Br2 O NO2

Explanation / Answer

(a) KCl = ionic = K+ and Cl-

(b) P4 = non polar covalent molecule and exist in tetrahedral structure

(c) BF3 = non polar covalent as dipole moment is zero.

(d) SO2 is polar covalent

(e) Br2 = non polar covalent

(f) NO2 is a polar covalent
