ABoiling points shift as liquids heat
BSome vapour never reaches the condenser
CCondensers always add trace impurities
DOthers would need zero partial pressure
Answer & Solution
Correct answer: D. Others would need zero partial pressure
Every volatile component keeps some partial pressure, so some of it always enters the vapour with the desired one.
