    Electron density on more electronegative atom I.e Oxyge , is less. This increase the O-H bond polarity. Hence the the liberation of H+ is easier as the ArCOO- ions stabily I higher than that of CH3CHOO- ion

    Due to steric hindrance and +i-effect in ketone and not in aldehyde

    1Thank You

    Deepa Chanwariya 7 years, 9 months ago

    Because Electrophilicity of aldehyde is higher than ketone . the positive charge on carbon of aldehyde is only stabilised by one alkyl group whereas in ketone two alkyl group stabilise the positive charge and decrease the reactivity.
