Question

Which of the following liquid pairs shows a positive deviation from Raoult's law

Options:

A . Water-nitric acid

B . Benzene-methanol

C . Water-hydrochloric acid

D . Acetone-chloroform

Answer: Option B
:
B
(a) Water-Nitric acid solution shows negative deviation from Raoult's law due to hydrogen bonding
(b) Benzene-methonol solution shows positive deviation due to formation hydrogen bonding
(c) Water-HCl solution shows negative deviation due to formation of hydrogen bonding
(d) Acetone-Chloroform solutions shows negative deviation due to formation of hydrogen bonding
it is prudent to remember some of these examples of solutions showing positive and negative deviations from Rault's law along with examples of ideal solutions
