Question

State True or False.

Dipole moment of $HF$ is less than that of $HCl$ because of shorter bond length of $HF$.

• A. True
• B. False

Answer 1

The correct option is B False

The given statement is False.
Dipole moment of HF is more than that of HCl because of higher electronegativity difference.
Note: Dipole moment is directly proportional to the electronegativity difference. Electronegativity difference between H and F is $4.0-2.2=1.8$. Electronegativity difference between H and Cl is $3.0-2.2=0.8$
