Which reagent is capable of giving test both of Aldehyde and ketones

Question

Which reagent is capable of giving test both of Aldehyde and ketones (A) Tollen reagent (B) Fehling solution (C) 2, 4 dinitrophenylhydrazine (D) Shift reagent

Tardigrade Admin · Accepted Answer

Both aldehydes and ketone reacts with 2, 4 DNP to form yellow, orange or red ppt. of 2, 4-dinitrophenylhydrazones. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/bfd0df8ed438815ba15d724ca0174456-.jpeg" /> with Fehling solution, Shiff’ s reagent and Tollen reagent only aldehyde reacts. These are distinguishing test for aldehyde and ketones.

Q. Which reagent is capable of giving test both of Aldehyde and ketones

Tollen reagent

Fehling solution

2, 4 dinitrophenylhydrazine

Shift reagent

Both aldehydes and ketone reacts with $2, 4 D NP$ to form yellow, orange or red $ppt$ . of $2, 4$ -dinitrophenylhydrazones.
