Please anyone help me ASAP ! Thanks :)

Answer 11

okay so Q 5 part C.
1 it consists of carbonly group.
2 ( D gave no reaction with tollens ragent ,we know that aldehyde react with tollens tagent as its not reacting and it has a carbonyl group) its a ketone as an orange ppt is formed.
3 when seconday alcohols oxidise they give ketone. so draw a seconday alcohol.

Answer 12

C(i) 2,4-DNPH will ONLY work for carbonyl groups (aldehyde and ketone) and will form orange ppt for BOTH the aldehyde and ketone.

since they say D gave no reaction to tollen's reagent,
ketone because tollen's reagent will only work for aldehydes and will form silver mirror during observations,

(ii) No reaction since I've said that ONLY aldehyde will react with tollen's reagent
