Question

An organic compound of molecular formula C3H6O does not produce any precipitate with 2, 4-dinitrophenyl hydrazine and does not react with sodium metal. This compound is (A) CH3COCH3 (B) CH2=CH-OCH3 (C) CH3CH2CHO (D) CH2=CHCH2OH

Tardigrade Admin · Accepted Answer

Negative reaction with 2, 4- dinitrophenylhydrazine indicates absence of aldehydic (option a) and ketonic (option c) group, while negative reaction with metallic sodium indicates absence of an alcoholic group (option b), hence the organic compound, C 3 H 6 O is CH 2= CHOCH 3

Q. An organic compound of molecular formula $C_{3} H_{6} O$ does not produce any precipitate with 2, 4-dinitrophenyl hydrazine and does not react with sodium metal. This compound is

$C H_{3} COC H_{3}$

$C H_{2} = C H - OC H_{3}$

$C H_{3} C H_{2} C H O$

$C H_{2} = C H C H_{2} O H$

Negative reaction with 2, 4- dinitrophenylhydrazine indicates absence of aldehydic (option a) and ketonic (option c) group, while negative reaction with metallic sodium indicates absence of an alcoholic group (option b), hence the organic compound, $C_{3} H_{6} O$ is $C H_{2} = C H OC H_{3}$
