Question

Which of the following solution can form maximum boiling azeotrope?

• A. $HCl+H_{2}O$
• B. $CH_{3}OH+H_{2}O$
• C. $C_{2}H_{5}OH+H_{2}O$
• D. $C_{6}H_{5}Cl+C_{6}H_{5}Br$

Answer 1

Answer: (A)

$HCl_{SA}H_{2}O \rightarrow \underset{Ionicinteraction}{\underline{Cl^{-}}}+H_{3}O^{\oplus}$
Because of ionic interaction (Greater interaction) it show negative deviation from Raoult's law.
