Question
Dr. O’Malley discovered three different compounds P, Q and R from the oxidation
reaction of an alcohol in the laboratory respectively. A bright coloured precipitate
was formed from compound P and Q when treated with 2,4-dinitrophenylhydrazine
while compound R showed negative result. Meanwhile, when compound P react
with Fehling's solutions, red brown precipitate was formed and vice versa for
compound Q. He also noticed further oxidation of compound P will produce
compound S that has fruity scent when react with methanol.
Suggest the possible condensed structure of compound P, Q and R and write its
IUPAC name.
Identify why compound R showed negative result when treated with 2,4-
dinitrophenylhydrazine.
