Question by M-Z: help! aromatic carbonyl compounds…?
(A) is a mono-substituted aromatic carbonyl compound, optically inactive, of formula C9H10O, which
has been evaluated as a drug candidate for the treatment of type 2 diabetes.

thank you so much.

– (A) gives a positive silver mirror test with Tollens’ reagent.
– (A) is oxidised to (B) by Fehling’s solution.
– (B) reacts with methanol in the presence of H+ catalyst to give (C) of formula C10H12O2 and water.
– (A) reacts with hydrazine (NH2-NH2) to give (D) of formula C9H12N2 and water.

Identify (A), (B), (C) and (D) giving structures and a brief explanation on how you arrived at those
structures.

(A) is an AROMATIC COMPOUND HAVING EMPIRICAL FORMULA C8H10O. I may suppose a lot of possible isomers….
IS (A) AN ALCOHOL? AN ETHER? AN CARBONYLIC COMPOUND?
Really, there is a set of experimental overcomes which leads me to determinate molecular structure of (A).

CLUE N.1)
IT RESULTS A CARBONYLIC COMPOUND, then I HAVE TO EXCLUDE “Cyclic Acetals” AND “Benzopyran Alcohols” ; “Ethers” are yet excluded by empirical formula itself.

CLUE N.2)
IT RESULTS OPTICALLY INACTIVE, then it hasn’t Chiral Centers and I CAN’T CONSIDER “Alpha-Phenyl-Propanal”.

CLUE N.3)
IT GET POSITIVE REMARK TO Tollens’ Test, the I CAN’T CONSIDER KETONEs LIKE “Phenyl-propanone”.

CLUE N.4)
IT GET POSITIVE REMARK TO Fehling’s Test, the I HAVE TO CONSIDER AROMATIC ALDEHYDEs LIKE “Beta-Phenyl-Propanal”.
Now, “BETA-PHENYL-PROPANAL” is (A) and it has to turn into (B) LIKE “BETA-PHENYL-PROPANOIC ACID”.

CLUE N.5)
(B) TAKES PART TO Esterification (STRONG ACIDIC MEDIUM) WHERE IT MEET Methanol (e.g. CH3OH) AND IT FORMS (C) AS “METHYL BETA-PHENYL-PROPANOATE”.

CLUE N.5)
(A) TAKES PART TO Acylic Addiction (MILD ACIDIC MEDIUM) WHERE IT MEET Hydrazine (e.g. N2H4) AND IT FORMS (D) AS “BETA-PHENYL-PROPANALDHYDRAZONE”.
