Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The heavy organic liquid obtained by the reaction of acetophenone with sodium hypochlorite produces a foul-smelling compound when heated with aniline and ethanolic potassium hydroxide. Reason (R): Acetophenone undergoes the haloform reaction with sodium hypochlorite to form chloroform, which then g
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true but (R) is not the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
A. Both (A) and (R) are true and (R) is the correct explanation of (A).
Step-by-step solution
Acetophenone ( C ₆ H ₅ COCH ₃ ) contains a methyl ketone group. When treated with sodium hypochlorite ( NaOCl ), it undergoes the haloform reaction to yield sodium benzoate and chloroform ( CHCl ₃ ). Chloroform is a heavy organic liquid. When chloroform is heated with a primary amine such as aniline ( C ₆ H ₅ NH ₂ ) and ethanolic potassium hydroxide, it undergoes the carbylamine reaction. The product of the carbylamine reaction is phenyl isocyanide ( C ₆ H ₅ NC ), which is characterized by a highly offensive or fou
