Indicate the direction of polarity of each of the following covalent bonds. Please just write a + or - not the bonds.
1. C O
2. O Cl3. O F4. C N5. Cl C6. S H7. S Cl

1. C+ O-

2. O+ Cl-

3. O+ F-

4. C+ N-

5. Cl- C+

6. S- H+

7. S+ Cl -

Explanation:

Electronegativity determines the polarity . There may be two atoms in a bond with high electronegativity, in such cases the positive charge is given to atom with comparatively lower electronegativity. Electronegativity determines the easiness with which an atom attract electrons in a chemical bond. A polar bond is formed when the difference in the electronegativity of two combining atoms is between 0.4 and 1.7. The correct direction is

1. C+ O-

2. O+ Cl-

3. O+ F-

4. C+ N-

5. Cl- C+

6. S- H+

7. S+ Cl -
