Wired Faculty App

Suggest the most important type of intermolecular attractive interaction in the following pairs.
(i) n-hexane and n-octane.
(ii) I₂ and CCl_4.(iii) NaCl O₄ and water.
(iv) methanol and acetone.
(v) acetonitrite (CH₃ CN) and acetone (C₃H₆O).

Solution

Answer:

(i) The intermolecular attractive forces between the A-A and B-B are nearly equal to those between A-B.
(ii) A-B interactions are weaker than those between A-A or B-B.
(iii) A-B interactions are more than those between A-A and B-B.
(iv) A-B interactions are less than A-A and B-B interactions.
(v) A-B interactions are more than A-A and B-B interactions.
