Which of the following forms an ideal solution? This question has multiple corre

Ideal solutions obey Raoult's law and are formed when intermolecular interactions between components are similar to those in the pure components. Bromoethane and chloroethane are both haloalkanes with similar molecular sizes and polarities, leading to nearly identical intermolecular forces (dipole-dipole and dispersion), hence they form an ideal solution. Other options: A (Acetone and phenol) form hydrogen bonds leading to negative deviation; C (CCl4 and SiCl4) and D (Bromobenzene and chlorobenzene) are also ideal, but B is a classic example.
