Somebody bets you that at 60"C, the vapor pressure of 1,2-dichlorobenzene (1,2- DCB) is smaller than that of 1,4-dichlorobenzene (1,4-DCB), but that at 20"C, the opposite is true; that is, pr*(1,2-DCB, 20°C) > pr*(1,4-DCB, 20°C). Is this person right? If yes, at what temperature do both compounds exhibit the same vapor pressure?  

Answer rating: 100% (QA)

At 20 degree C The melting point of 12 DCB 17 degree Cnad that of 14 DCB 531 degree C So at 20 degre... View the full answer
