Question

The highest dipole moment is of:

• A. $CF_{4}$
• B. $CH_{3}OH$
• C. $CO_{2}$
• D. $CH_{3}F$

Answer 1

Answer: (D)

$CH_{3}F$

Answer 2

$CF _{4}$ is tetrahedral and $CO _{2}$ is linear. They are symmetrical molecules with zero dipole moment. Fluorine is more electronegative than oxygen. Hence, the dipole moment of $CH _{3} F$ is more than $CH _{3} OH$.
