If the electronegativity difference between bonded atoms is zero, the bond between the two atoms is:
- A
Polar
- B
Partially Ionic
- C
Non-polar
- D
Both B and C
Explanation:
If the electronegativity difference between bonded atoms is zero, the bond between the two atoms is non-polar.
This option is not correct. If the difference is greater than 0.4, the bond becomes polar.
This option is also not correct. If the difference is greater than 1.7, the bond becomes ionic.
This option is incorrect. A polar bond forms when the electronegativity difference is between 0.4 and 1.7, causing unequal sharing of electrons.
This option is incorrect. A bond is considered partially ionic when the electronegativity difference is significant, typically greater than 1.7, leading to electron transfer.
This option is correct. When the electronegativity difference between bonded atoms is zero, the electrons are shared equally, resulting in a non-polar bond.
This option is incorrect. Both statements cannot be true simultaneously because a bond cannot be both non-polar and partially ionic.
