    Alkyl groups are weakly electron donating, they tend to destabilise anions. This is because they will be "pushing" electrons towards a negative system which is unfavourable electrostatically. Hence, the anion of a ketone, where there are extra alkyl groups is less stable than that of an aldehyde So 2nd less stable than 1st

    carbanion stability order 1>2>3>4>5 Explanation:- In the ester, there is also a resonance donation from the alkoxy group towards the carbonyl that competes with the stabilisation of the enolate charge. This makes the ester enolate less stable than those of aldehydes and ketones so esters are even less acidic.
