Question

When acetone and chloroform are mixed together, which of the following observations is correct ?

• A. $A - A$ and $B - B$ interactions are stronger than $A - B$ interactions
• B. $A - A$ and $B - B$ interactions are weaker than $A - B$ interactions
• C. $A -A$, $B - B$ and $A - B$ interactions are equal
• D. The liquids form separate layers and are immiscible

Answer 1

Answer: (B)

$A - A$ and $B - B$ interactions are weaker than $A - B$ interactions

Answer 2

When acetone and chloroform are mixed together, a hydrogen bond is formed between them which increases intermolecular interactions. Hence, $A - B$ interactions are stronger than $A - A$ and $A - B$ interactions.
