The electronegativity of N O and F are 3.0 3.5 and 4 respectively according to the Pauling's scale. The electronegativity difference between N and F is greater than the difference between O and F. So, the prior bond is expected to be more polar.
The As-F bond will be more polar than the As-Cl bond. This is because fluorine is more electronegative than chlorine, leading to a greater difference in electronegativity between the atoms and a more polar bond.
A carbon-oxygen bond is more polar than a carbon-hydrogen bond, because the difference in electronegativity between carbon and oxygen is greater than the difference in electronegativity between carbon and hydrogen.

The O-F bond is more polar than the O-S bond. This is because fluorine (F) is more electronegative than sulfur (S), leading to a greater difference in electronegativity between oxygen (O) and fluorine compared to oxygen and sulfur, resulting in a more polar bond.
The P-Cl bond is more polar than the P-Br bond. This is because chlorine (Cl) is more electronegative than bromine (Br), so it attracts the shared electrons in the bond more strongly, leading to a greater difference in electronegativity and thus a more polar bond in P-Cl compared to P-Br.
The H-F bond is more polar than the H-I bond because F (fluorine) is more electronegative than I (iodine). It thus attracts the shared electrons more than does the I, making it a more polar bond.
The As-F bond will be more polar than the As-Cl bond. This is because fluorine is more electronegative than chlorine, leading to a greater difference in electronegativity between the atoms and a more polar bond.
A phosphorus-fluorine bond is more polar than a phosphorus-chlorine bond. Fluorine is more electronegative than chlorine, so it withdraws electrons more strongly in a covalent bond, resulting in a greater difference in electronegativity between phosphorus and fluorine compared to phosphorus and chlorine.
A carbon-oxygen bond is more polar than a carbon-hydrogen bond, because the difference in electronegativity between carbon and oxygen is greater than the difference in electronegativity between carbon and hydrogen.

The O-F bond is more polar than the O-S bond. This is because fluorine (F) is more electronegative than sulfur (S), leading to a greater difference in electronegativity between oxygen (O) and fluorine compared to oxygen and sulfur, resulting in a more polar bond.

The P-Cl bond is more polar than the P-Br bond. This is because chlorine (Cl) is more electronegative than bromine (Br), so it attracts the shared electrons in the bond more strongly, leading to a greater difference in electronegativity and thus a more polar bond in P-Cl compared to P-Br.
The OH bond is more polar than the NH bond because oxygen is more electronegative than nitrogen, leading to a greater difference in electronegativity between oxygen and hydrogen. This means the OH bond has a greater separation of charge and greater polarity than the NH bond.
Se-Cl bonds
Bromine will form a more polar bond with phosphorus compared to iodine. This is because bromine is more electronegative than iodine, resulting in a greater difference in electronegativity between bromine and phosphorus, making the bond more polar.
The chemical bond between carbon-chlorine has an electronegativity difference of 0.61. The bond between carbon-hydrogen has a difference of 0.35, thus is less polar than the carbon-chlorine bond.
