Part 2   (0.5 point)

See Hint

Are any of the bonds formed between the following pairs of atoms ionic?

Choose one or more:

O and H

Ca and Cl

P and F

B and H

C and Cl

Answer 1

Ca-Cl and P-F bond are ionic.

81 B-ce electronegativity difference AX = 3-2 = 1 C-F at DX = 4-2.5 = 1.5 Cl-o o x = 3.5-3.0 = 0.5 H-F LAX = 4.0-2.1 - 1.9 @n analf is most polas due to highest electronegativity difference. 02. 0-H DX = 3.5-2.1 = 1:4 Ca-ce Ax =3-1 =2 Tonic P- F . ox =4-2-1 = 1.9 Tonic B-4 SX = 2.1-2.0- 0-1 c-ce o X - 3-2.5 = 0.5 for ionic bond, OX > 1.8
