Question

Mixture of ethanol and acetone shows positive deviation from Raoult’s Law

Answer 1

YES, BECAUSE ATTRACTION BETWEEN A-A (HYDROGEN BONDING i.e;O-H) and IS MUCH STRONGER THAN A-B ATTRACTION. HERE , A AND B ARE THE RESPECTIVE COMPOUNDS GIVEN IN THE QUESTION. .......pls correct me if I'm wrong.

Answer 2

the mixture of ethanol and acetone shows positive deviation from the Raoults law because of the presence of hydrogen bond in them

Explanation:

• There is a pair of grown pair in the oxygen of ethanol. These are added to the the weekend orbital which is present in hydrogen atom in case of acetone.
• As a result of this there is hydrogen bond which is formed behind the mixture of ethanol and acetone and as a result of this it shows positive deviation from the Raoults law
