Question

The molecule with the highest dipole moment among the following is:

• A. $N{H}_3$
• B. $N{F}_3$
• C. $CO$
• D. $HF$

Answer 1

The correct option is D $HF$

Generally, dipole moment is directly proportional to electronegativity. So, among these $HF$ has highest dipole moment value of 1.9 D.
Dipole moment value for, $N{F}_3=0.23D$
$N{H}_3=1.46D$
$CO=0.12D$
