Question

Answer the following by appropriately matching the lists based on the information given in the paragraph.

List - I	List - II
(P) $C_{2} H_{5} Br + C_{2} H_{5} Cl$	(1) $Δ H_{mix} = 0$
(Q) $CH_{3} COCH_{3} + C_{2} H_{5} OH$	(2) $Δ H_{mix} > 0$
(R) $CH_{3} COCH_{3} + CHCl_{3}$	(3) $Δ H_{mix} < 0$
(S) $H_{2} O + C_{2} H_{5} OH$	(4) can form maximum boiling azeotrope
	(5) can form minimum boiling azeotrope

Which of the following is an CORRECT match ?

TestHub · Accepted Answer

P) C₂H₅Br + C₂H₅Cl forms an ideal solution, so $Δ H_{mi x} = 0$ .

Q) CH₃COCH₃ + C₂H₅OH shows positive deviation, so $Δ H_{mi x} > 0$ and forms a minimum boiling azeotrope.

R) CH₃COCH₃ + CHCl₃ shows negative deviation, so $Δ H_{mi x} < 0$ and forms a maximum boiling azeotrope.

S) H₂O + C₂H₅OH shows positive deviation, so $Δ H_{mi x} > 0$ and forms a minimum boiling azeotrope.

Therefore, the correct match is P $\to$ 1, Q $\to$ 2,5, R $\to$ 3,4, S $\to$ 2,5.
