Question
Indicate whether the following statement is true or false. Justify your answer in not more than three lines. The dipole moment of $\mathrm{CH}_3 \mathrm{F}$ is greater than that of $\mathrm{CH}_3 \mathrm{CL}$.
✓

Answer

True. Explanation: This is because $\text{C}-\text{F}$ bond is more polar than $\text{C}-\text{Cl}$ bond due to larger electronegativity of F than Cl. As a result, the resultant dipole moment of $\mathrm{CH}_3 \mathrm{F}$ is more.
