Question

value: 5
match the type of bond with the correct difference in electronegativity values.
a. electronegativity difference is between 0-0.4
b. electronegativity difference is greater than 1.8
c. electronegativity difference is between 0.5-1.7

1. non-polar-covalent bond\ta
2. polar-covalent bond\ta
3. ionic bond\ta

Explanation:

• Non - polar - covalent bonds occur when the electronegativity difference between atoms is very small (0 - 0.4), so it matches with option a.
• Polar - covalent bonds have an electronegativity difference in the range of 0.5 - 1.7, so it should match with option c.
• Ionic bonds form when the electronegativity difference is relatively large, greater than 1.8, so it should match with option b.

Answer:

1. Non - polar - covalent bond: a. Electronegativity difference is between 0 - 0.4
2. Polar - covalent bond: c. Electronegativity difference is between 0.5 - 1.7
3. Ionic bond: b. Electronegativity difference is greater than 1.8
