Answer : The direction of the polarity can be determined for any molecule on the basis of the atomic electro-negativity of the given molecule. Each polar bond has a dipole moment in it and it can be treated as a vector quantity that has a magnitude and direction both in it.For molecules, we can assign the direction of the polarity of more electro-positive to the most electro-negative. For more electro-positive, we can give a partial positive charge, while, for the more electro-negative we can give partial negative charge.These are electronegative values of the atoms given in the options;F = 3.98 Or = 3.44 Cl = 3.16 N = 3.04 C = 2.55 S = 2.58 H = 2.2 Answer 1) +C---Or-In this molecule of C is more electro-positive atom Or and Or has a higher electro-negativity. Thus, the partial positive charge goes on the C atom and partial negative charge on the atom of O. Answer 2) +Oh---Cl-Here, the O atom is more electro-positivity of the Cl atom, therefore, becomes part of the positive charge on it while the Cl atom is with high electro-negativity in comparison to O. therefore, It has partial negative charge.Answer 3) +O---F-Now, in this molecule O is less electronegative than the atom of F therefore, we obtain the positive charge partial. Whereas, the F atom has a greater electro-negativity in comparison too atom. Therefore, it has partial negative charge.Answer 4) +C---N-C atom is more electro-positive it as a comparison with the N atom, is obtained by the partial positive charge, while N is more electro-negative of C, therefore, has partial negative charge.Response 5) -Cl---C+Now, Cl has the highest electro-negativity in its atom compared with the C atom so that the profits of the partial negative charge, while C is less electro-negative is obtained by the positive charge partial.Response 6) -S---H+Hydrogen atom is more electropositive as well, you get the load partial positive about himself; whereas, the S atom is less electro-positive than H. Thus, you get the negative charge partial.Response 7) +S---Cl-Here, S is less electro-negative, in comparison with Cl and therefore, obtains the positive charge partial on itself; while Cl has a higher electro-negativity of S. Thus, you get the negative charge partial.
