Ethyl alcohol forms hydrogen bonding with itself, hence it will not form ideal solution with C2H5I.

1. Ethyl alcohol forms hydrogen bonding with itself.
2. It will not form ideal solution with C2H5I.
3. ΔHmixing = 0
4. ΔHmixing = 0

Correct answer: It will not form ideal solution with C2H5I.

Solution

Ethyl alcohol forms hydrogen bonds with itself, which are disrupted when mixed with C2H5I, leading to non-ideal behavior. Hence, it will not form an ideal solution.
