Question

The electronegativity value of $C=2.5$ and $F=4.0$.
$I$. Carbon tetrafluoride is a non-polar molecule.
$II$. Carbon tetrafluoride molecules have a 4 polar $C-F$ bonds and a tetrahedral geometry.

• A. Statement $I$ is true, Statement $II$ is true and is a correct explanation of the phenomena described in $I$
• B. Statement $I$ is true, Statement $II$ is false
• C. Statement $I$ is false, Statement $II$ is true
• D. Statement $I$ is false, Statement $II$ is false

Answer 1

The correct option is A Statement $I$ is true, Statement $II$ is true and is a correct explanation of the phenomena described in $I$

$C{F}_4$ have net dipole = 0, thus non polar.

Yes $C{F}_4$ have $4C-F$ polar bonds as $F$ being more electronegative attracts the shared paired of electrons towards itself, hence polar and $C{F}_4$ have a tetrahedral geometry.
