The delta notation that indicates the direction of polarity for each of the given covalent bonds are:
δ+ C-O δ-
δ- O-Cl δ+
δ+ O-F δ-
δ+ C-N δ-
δ+ C-Cl δ-
δ- S-H δ+
δ+ S-Cl δ-
Polar bonds are those in which the atoms of their elements have a difference in electronegativities.
Now, the more electronegative atom is the one that can attract pair of bonded electrons to itself and as a result will possess a partial negative charge. In contrast, the less electronegative atom will possess a partial positive charge.
Finally, the direction of polarity of covalent bonds will flow from the less electronegative atom to the atom that is more electronegative.
Let us state the electronegativities of all the elements stated in this question;
1) Electronegativity of Carbon; C = 2.5
2) Electronegativity of Oxygen; O = 3.5
3) Electronegativity of Chlorine; Cl = 3
4) Electronegativity of Fluorine; F = 4
5) Electronegativity of Nitrogen; N = 3
6) Electronegativity of Sulphur; S = 2.5
7) Electronegativity of Hydrogen; H = 2.1
Thus;
1) C-O; O is more electronegative than C an as such will have the charge δ- while C will have δ+.
2) O-Cl; O is more electronegative than Cl an as such will have the charge δ- while Cl will have δ+.
3) O-F; F is more electronegative than O an as such will have the charge δ- while O will have δ+.
4) C-N; N is more electronegative than C an as such will have the charge δ- while C will have δ+.
5) Cl-C; Cl is more electronegative than C an as such will have the charge δ- while C will have δ+.
6) S-H; S is more electronegative than H an as such will have the charge δ- while H will have δ+.
7) S-Cl; Cl is more electronegative than S an as such will have the charge δ- while S will have δ+.
