Which of the following has highest dipole moment?

${\mathrm{CH}}_3\mathrm{F}$ have the largest/highest dipole moment.

${\mathrm{CF}}_4$ has a tetrahedral shape and symmetrical hence there is zero dipole moment.

 ${\mathrm{CO}}_2$ is linear so it also has dipole moment zero. 

${\mathrm{CH}}_3\mathrm{OH}$ has less dipole in comparison with ${\mathrm{CH}}_3\mathrm{F}$ 

Hence, the correct option is option (D) CH₃F.
