Question

give reason HF is a polar molecule​

Answer 1

Answer:H and F combine with covalent bond to form HF

Fluorine has high electronegativity so it attracts the electrons towards itself .therefore a partial negative charge is created around fluorine.so it becomes polar in nature.

Answer 2

The electronegativity difference between the atoms in a molecule of HF is non-zero then the molecule is polar.

Explanation :

Electronegativity : It is a chemical property which measures the ability of an atom to attract an electrons towards itself.

Electronegativity difference : The difference in the electronegativity of the two atoms determines their polarity.

When the electronegativity difference between the two atoms is zero then the molecule is non-polar.

When the electronegativity difference between the two atoms is non-zero then the molecule is polar.

Thus, the electronegativity difference between the atoms in a molecule of HF is non-zero then the molecule is polar.
