Carbon tetrachloride has no net dipole moment because of

What is the dipole moment in a molecule? Describe the dipole moment of diatomic molecules.

If compound $MX_4$ has $\mu = 0$,then the most probable geometry will be:

Which of the following compounds will show a dipole moment?

The molecular size of $ICl$ and $Br_2$ is approximately the same,but the $b.p.$ of $ICl$ is about $40 \ ^oC$ higher than that of $Br_2$. This is because:

Bond distance in $HF$ is $9.17 \times 10^{-11} \ m$. Dipole moment of $HF$ is $6.104 \times 10^{-30} \ Cm$. The percentage ionic character in $HF$ will be : .............. $\%$
(electron charge $= 1.60 \times 10^{-19} \ C$)
