When 1 mole of benzene is mixed with 1 mole of toluene, the vapours will contain
- A Equal number of moles of benzene and toluene since it is an ideal solution
- B Higher percentage of benzene
- C Equal mass of benzene and toluene since it is an ideal solution
- D Higher percentage of toluene
Answer & Solution
Correct Answer
(B) Higher percentage of benzene
Step-by-step Solution
Detailed explanation
Benzene is more volatile than toluene, which means the vapour pressure of pure benzene is greater than that of pure toluene (\(P^{\circ}_B > P^{\circ}_T\)). Given that \(1\) mole of benzene is mixed with \(1\) mole of toluene, the mole fractions in the liquid phase are…

- Two statements, one Assertion and the other Reason are given. Identify the correct option
Assertion: Primary and secondary amides on treatment with \(\mathrm{Br}_2\) and alcoholic NaOH yield primary and secondary amines respectively and the reaction involves stepping down the series.
Reason: The reaction occurs due to the migration of alkyl group from Carbonyl carbon atom to the Nitrogen atom with elimination of carbonyl group as the carbonate salt.COMEDK 2025 Medium - Which of the following tests may be used to distinguish between phenol and cyclohexanol?COMEDK 2024 Easy
