QNEET-2020-Ch-672: NEET 2020 Chemistry - Class 12 NEET-2020-Ch-672 Solution: The mixture which shows positive deviation from Raoult's law…
The mixture which shows positive deviation from Raoult's law is: Benzene + Toluene Acetone + Chloroform Chloroethane + Bromoethane Ethanol + Acetone
Multiple Choice Options
- A Benzene + Toluene
- B Acetone + Chloroform
- C Chloroethane + Bromoethane
- D Ethanol + Acetone
Step-by-Step Verified Solution
Pure ethanol molecules are hydrogen bonded. On adding acetone, its molecules get in between the ethanol molecules and break some of the hydrogen bonds between them. This weakness the intermolecular attractive interactions and the solution shows positive deviation from Raoult's law.
