APCHEM-ALPXAL

Given the table below:

$\text {Bond Type}$ $\text {Average Bond Enthalpy}$ $\text {(kJ/mol)}$
$C - C$ 413
$C = C$ 614
$C \equiv C$ 839

$\$
Which of the following describes the relationship between the average bond enthalpy and the relative strength of bonds?

A

As the strength of the bond increases, the average bond enthalpy increases.

B

As the strength of the bond increases, the average bond enthalpy decreases.

C

As the strength of the bond increases, the average bond enthalpy does not change.

D

There is no direct relationship between bond strength and bond enthalpies.
