Which compound exhibits the maximum dipole moment among the following?

If $HCl$ were purely ionic,its expected dipole moment would be $6.12 \, D$. However,the experimental dipole moment is $1.03 \, D$. Calculate the percentage ionic character. (in $\%$)

Which molecule has the largest dipole moment?

$BF_3$ and $NF_3$ both are covalent compounds but $NF_3$ is polar whereas $BF_3$ is non-polar. This is because
