Question

Assertion (A): The synthesis of urea from ammonium cyanate by Wöhler marked the first laboratory synthesis of an organic compound from inorganic precursors. Reason (R): Kolbe's synthesis of acetic acid involved carbon derived strictly from biological sources.

Prashant Kotian · Accepted Answer

Correct answer: C. Wöhler's synthesis of urea (1828) disproved the Vital Force Theory by using inorganic precursors (Ammonium cyanate). Kolbe synthesized acetic acid from its constituent elements (C, H, O) in 1845, further disproving the theory; thus, R is false as the carbon was not of biological origin.
