Q88 (NDA-II/2023) Science & Technology › Basic Science (Physics, Chemistry, Biology) Official Key

Which one of the following is NOT an example of organic compound ?

Explanation

Ammonium cyanate (NH4CNO) is classified as an inorganic compound. It is an ionic salt consisting of the ammonium cation and the cyanate anion. Although it contains carbon, it lacks the C-H bonds characteristic of most organic compounds and is historically categorized as inorganic.

  • Historical Significance: In 1828, Friedrich Wöhler synthesized Urea (an organic compound) by heating Ammonium cyanate. This experiment was revolutionary as it disproved the 'Vital Force Theory,' showing that organic compounds could be synthesized from inorganic precursors.
  • Marsh gas: This is Methane (CH4), the simplest organic hydrocarbon.
  • Urea: An organic compound (carbamide) naturally found in mammals and synthesized for fertilizers.
  • Cane sugar: Sucrose (C12H22O11) is a complex organic carbohydrate.

Thus, Ammonium cyanate is the only inorganic substance among the given options.
