NEET Aldehydes Ketones and Carboxylic Acids — Set 6

Question 1

What is the common name of $ \ce{CH3CH2CH2CH2COOH} $?

Accepted Answer

The compound $ \ce{CH3CH2CH2CH2COOH} $ (pentanoic acid in IUPAC) is historically known as valeric acid in common nomenclature.

Question 2

Which alkene produces 3-methylbutanal and methanal upon ozonolysis?

Accepted Answer

4-Methylpent-1-ene ($ \ce{CH2=CHCH2CH(CH3)2} $) cleaves at the double bond, forming methanal ($ \ce{HCHO} $) and 3-methylbutanal ($ \ce{(CH3)2CHCH2CHO} $).

Question 3

Which of the following is a product of the Rosenmund reduction of propanoyl chloride?

Accepted Answer

Rosenmund reduction ($ \ce{H2, Pd/BaSO4} $) converts acyl chlorides to aldehydes. Propanoyl chloride ($ \ce{CH3CH2COCl} $) yields propanal ($ \ce{CH3CH2CHO} $).
