Answer:
bcz due to steric hindrance and electronic factor
Explanation:
in aldehyde small hydrogen is attach to one side of carbonyl gp while a larger R gp is fix towards other side .while in ketone R gp is on both sides so steric hindrance is less in aldehyde than ketone.
second ly aldehyde has one alkyl gp to supply electrons to positive ly charge carbonyl carbon while ketone has 2. greater the electron supply to carbonyl carbon less is the positive charge on this atom weaker it will as nucleus
