Question

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

A - O and H
B - C and Cl
C - B and H
D - P and F
E - Ca and Cl

Answer 1

The bonds formed between the pairs of atoms are likely to be either polar covalent or ionic, depending on the electronegativity difference between the atoms.

Step-by-step explanation:

Out of the pairs of atoms listed:

1. A - O and H: This bond is likely to be polar covalent because oxygen and hydrogen have a significant electronegativity difference.
2. B - C and Cl: This bond is likely to be polar covalent because there is a considerable electronegativity difference between carbon and chlorine.
3. C - B and H: This bond is likely to be polar covalent because there is a notable electronegativity difference between boron and hydrogen.
4. D - P and F: This bond is likely to be ionic because phosphorus and fluorine have a large electronegativity difference.
5. E - Ca and Cl: This bond is likely to be ionic because calcium and chlorine have a significant electronegativity difference.
