Choose the correct statement from the options given below:

The solution of benzene and toluene is an example of an ideal solution.

The correct answer is Option (1) → The solution of benzene and toluene is an example of an ideal solution.

OPTION -1. The solution of benzene and toluene is an example of an ideal solution.
This statement is correct.
Benzene and toluene have similar molecular size and intermolecular forces, so their interactions are similar. Hence they form an ideal solution and obey Raoult’s law

OPTION 2. For an ideal solution, ΔHmix > 0.
This statement is incorrect.
For an ideal solution:
ΔHmix = 0 (no heat is absorbed or released)

OPTION 3. Ideal solutions do not obey Raoult's law.
This statement is incorrect.
Ideal solutions obey Raoult’s law at all compositions.

OPTION 4. The solution of water and alcohol is an example of an ideal solution.
This statement is incorrect.
Water and alcohol show strong hydrogen bonding and deviate from Raoult’s law, so they form a non-ideal solution.
