JEE Main 2020Chemical Bonding and Molecular Structure Question with Solution

JEE Main 2020 (02 Sep Shift 2)

Question

Match the type of interaction in column A with the distance dependence of their interaction energy in column B:

A B
(i) ion - ion  (a) 1r
(ii) Dipole - dipole (b) 1r2
(iii) London dispersion (c) 1r3
  (iv) 1r6

Choose an option

Show full solutionCorrect option: D
Correct answer
D(i) – (a); (ii) – (c); (iii) – (d)

Step-by-step explanation

(i) ion-ion interaction energy is inversely proportional to the distance between ions 1r
(ii) dipole-dipole interaction energy is inversely proportional to the third power of r1r3
(iii) The interaction energy of London force is inversely proportional to sixth power of distance between two interaction particles 1r6
