Which of the following structures is not correctly matched?

A$$\alpha$$ - Methoxypropionaldehyde - $$H_3C-{\overset{H_3CO}{\overset{|}{CH}}}-\overset{O}{\overset{||}{C}}-H $$
B3-Hydroxybutanal - $$ CH_3-{\overset{OH}{\overset{|}{CH}}}-CH_2CHO$$
C4 - Oxopentanal - $$CH_3CH_2CH_2-{\overset{O}{\overset{||}{C}}}-CHO $$
Correct Answer
DDi-sec. -butylketone - $$CH_3CH_2-{\overset{CH_3}{\overset{|}{CH}}}-{\overset{O}{\overset{||}{C}}}-{\overset{CH_3}{\overset{|}{CH}}} - CH_2CH_3 $$

Solution

According to IUPAC counting no. should be given from functional group. Also aldehyde has grater ranking than ketone.

A compound has molecular formula $$C_6H_{12}O.$$ It does not reduce Tollens or Fehling's reagent, but gives a crystalline derivative with 2,4-dinitro-phenyl hydrazine. With alkali and $$I_2,$$ it gives yellow solid with a medicinal odour. Clemmensen reduction converts it to 2-methylpentane. The structural formula of the compound is most likely to be:
