Question

Classify these bonds as ionic, polar covalent, or nonpolar covalent p cl k br c c

Answer 1

Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,

Less than 0.4 then it is Non Polar Covalent

Between 0.4 and 1.7 then it is Polar Covalent

Greater than 1.7 then it is Ionic

For P and Cl,
E.N of Chlorine = 3.16
E.N of Phosphorous = 2.19
________

E.N Difference 0.97 (Polar Covalent)

For K and Br,
E.N of Bromine = 2.96
E.N of Potassium = 0.82
________

E.N Difference 2.14 (Ionic)

For C and C,
E.N of Carbon = 2.55
E.N of Carbon = 2.55
________

E.N Difference 0.00 (Non-Polar Covalent)
