Which of the following is correct?
  • A
    Bond order, $\propto\frac{1}{\text{bond length}}\propto\frac{1}{\text{bond enthalpy}}\propto\text{stability}$
  • B
    Stability, $\propto\frac{1}{\text{bond order}}\propto\frac{1}{\text{bond length}}\propto\frac{1}{\text{bond enthalphy}}$
  • C
    $\text{Stability}\propto\text{bond order}\propto\text{bond length}\propto\text{bond enthlpy}$
  • ✓
    $\text{Stability}\propto\text{bond order}\propto\text{bond enthalpy}\propto\frac{1}{\text{bond lenth}}$
✓

Answer

Correct option: D.
$\text{Stability}\propto\text{bond order}\propto\text{bond enthalpy}\propto\frac{1}{\text{bond lenth}}$
A general correlation useful for understanding the stabilities of molecules is that, with increase in bond order, bond enthalpy increases and bond length decreases. Stability increases with increase in bond order and bond enthalpy.
Therefore, $\text{Stability}\propto\text{bond order}\propto\text{bond enthalpy.}$ Stability increases with decrease in bond length. Therefore,
$\text{Stability}\propto\frac{1}{\text{bond length}}$
