Q14.5 P - Chemistry: Molecular Nature Of Matter And Change

Question

How are bond energy, bond length, and reactivity related to similar compounds?

Step-by-Step Solution

Answer

Bond energy decreases with increasing bond length. Shorter bonds are stronger bonds. Reactivity rises when bond energy rises.

Step 1: What are bond length and bond energy?

The distance between the nuclei of linked atoms is known as bond length. The enthalpy change required to break a bond in 1 mol of gaseous molecules is known as bond energy.

Step 2: What relationship is between bond energy, bond length, and reactivity for similar compounds?

These bond characteristics and reactivity are correlated among similar molecules. Bond energy increases as bond length rises (shorter bonds are stronger bonds). Reactivity rises when bond energy increases.
