Ques. 1JEE Main 2024, 8 April (Morning Shift)

Match List I with List II Choose the correct answer from the options given below:

  1. A-III, B-II, C-I, D-IV
  2. A-II, B-I, C-IV, D-III
  3. A-II, B-III, C-IV, D-I
  4. A-IV, B-III, C-II, D-I

Answer

(4) A-IV, B-III, C-II, D-I

Solution

A. Cl, S have the most negative egH in groups 17 and 16 (in the small F and O atoms the added electron is strongly repelled), so A-IV

B. Ge, As are metalloids, so B-III

C. Fr, Ra are the last members of groups 1 and 2 (largest atoms), so C-II

D. F, O head groups 17 and 16 (highest electronegativity), so D-I

Hence A-IV, B-III, C-II, D-I.

Answer: (4)
