Q1.Dipole moment of Aldehyde/Ketone is more than Alcohols.
Ans.In aldehyde/Ketone carbonyl group (C = O) has
p-electrons which are loosly held and shifts towards oxygen more thas electrons in Alcohols.

Q2.Aldehydes are more reactive than ketones towards nucleophlic substitution.
Ans.(a)Ketone has two alkyl group (+ I effect) makes less polar class_12_chemistry_useful_2 
(b)Heavy alkyl group in ketones show stric hindrance and become less reactive.

Q3.Benzaldehyde gives tollen’s test but not with fehling solution

Ans.Benzene ring show +R effect in benzaldehyde and make  class_12_chemistry_useful_2 more polar hence became strong oxidising agent which is only oxidise by strong tollen’s reagent but not with weak oxidsing agent like feliling solution.

Q4.p-fluorobenzoic acid is weaker acid than p-chlorobenzoic acid.
Ans.In p-flurobenzoic acid +R effect outweighs the – I effect of flurine (small size of 2p-orbital electron). But the pchlorobenzoic acid – I effect is more dominating (size of Cl atom 3p electrons) than +R effect.

Q5.Why carboxylic acid do not give the characteristics rection of carbonyl group > C = O.
Ans.In carboxylic acid the resonance structure makes it less electrophilic character than carbonyl group of aldehyde/ ketones.
