Ques. 1JEE Main 2024, 30 January (Morning Shift)

Choose the correct statements from the following : Choose the correct answer from the options given below :

  1. (B), (C), (E) only
  2. (A), (D), (E) only
  3. (C), (D), (E) only
  4. (A), (B), (C) only

Answer

(4) (A), (B), (C) only

Solution

(A): H2N-CH2-CH2-NH2 binds through both N (five-membered ring) ⇒ (A) is correct

(B): Hall–Héroult process: Al2O3 in molten cryolite (Na3AlF6) is electrolysed ⇒ (B) is correct

(C): silver is leached as [Ag(CN)2]- by CN- and air ⇒ (C) is correct

(D): Wilkinson catalyst [RhCl(PPh3)3] has triphenylphosphine, not phosphine (PH3) ⇒ (D) is incorrect

(E): Ca–EDTA and Mg–EDTA stability constants differ (so Ca2+, Mg2+ are estimated separately) ⇒ (E) is incorrect

∴ (A), (B), (C) only

Answer: (4)
