CH $_3$ -F $<$ CH $_3$ -Cl $>$ CH $_3$

CH $_3$ -Cl $>$ CH $_3$ -F $>$ CH $_3$

Explanation

To solve this problem, we need to understand the concept of bond enthalpy for the $C-X$ bonds, where $X$ is a halogen. $\newline$ Bond enthalpy is the energy required to break one mole of a bond in a gaseous molecule. $\newline$ The bond enthalpy generally decreases as the size of the halogen increases. This is because larger halogens form longer and weaker bonds with carbon. $\newline$ Let's analyze the
