Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Please attach an image file with your questions or mention it in the comment
This is the case when aldehydes and ketone are not reactive towards nucleophilic substitution as carboxylic aci acyl chlorides are ...plz expian the reason .
.....
second picture is just a reference
in case of aldehydes and ketones. aldehydes are more reactive than ketones as ketones possess steric hindrance and a two R groups.
but in case of aldehydes they posses a hydrogen which facilitate then Nucleophilic addition reaction. this is enhance in when acyl groups are present
so the order becomes acyl, then aldehydes and at last ketone
sir I am not asking this I am asking that why aldehyde and ketone are not reactive for nucleophilic substitution reaction
as compared to carboxylic acid ester anhydrides
the second picture which I have sent you they have explained through resonance
I yes, it is also a perfect explanation. as resonance increases, stability also increases. this leads to low reactivity
