Suggest the most important type of intermolecular attractive interaction in the following pairs : (i) n-hexane and n-octane(ii) I_2 and "CCl"_4 (iii) NaClO_4 and water (iv) methanol and acetone (v) acetonitrile (CH_3CN) and acetone (C_3H_6O). |

Answer» SOLUTION :(i) Both are non-POLAR. Hence, intermolecular interactions will be London DISPERSION forces. (ii) Same as (i). (iii) `NaClO_4`gives `NA^+` and `ClO_4^-`ions in the solution and water is a polar molecule. Hence,intermolecular interactions will be ion-dipole interactions. IV) Both are polar molecules. Hence, intermolecular interactions in them will be dipole-dipole interactions. (v) Same as (iv). |
