Q.

Match List-I with List-II.                         [2025]

  List-I   List-II
A. Solution of chloroform and acetone I. Minimum boiling azeotrope
B. Solution of ethanol and water II. Dimerizes
C. Solution of benzene and toluene III. Maximum boiling azeotrope
D. Solution of acetic acid in benzene IV. Vmix=0

 

Choose the correct answer from the options given below:

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

Ans.

(1)

(A)  Chloroform + acetone exhibits negative deviation from Raoult’s law i.e. form maximum boiling azeotrope.  

(B)  Water + ethanol exhibits positive deviation from Raoult’s law i.e. form minimum boiling azeotrope.  

(C)  Solution of benzene and toluene forms an ideal solution i.e. ΔVmix=0

(D)  Carboxylic acids dimerise in benzene because of intramolecular hydrogen bonding.
