Question

As the ΔEN for a particular bond increases, the character of the bond changes and this is often reflected in the behavior of a substance. The ΔEN for the K-Br bond is 2.0 and ΔEN for the Au-Br bond is 0.4. Match each statement about the K-Br and Au-Br bonds correctly to the descriptions.

The K-Br bond is more

The Au-Br bond is more

KBr is expected to have

AuBr3 is expected to have

Answer 1

The ΔEN values determine the nature of the K-Br and Au-Br bonds.

Step-by-step explanation:

The difference in electronegativity (ΔEN) between two bonded atoms can determine the type of bond and the behavior of a substance. In general, as the ΔEN increases, the bond becomes more polar and the substance exhibits different properties. In the case of the K-Br bond with a ΔEN of 2.0, it is expected to be more ionic in nature. On the other hand, the Au-Br bond with a ΔEN of 0.4 is expected to be more covalent in nature.
