Which of the following is wrong?

Options

A. (1) The word organic was originally used by the `18th` century chemists to describe the compounds of plant or animal origin (living sources) whereas inorganic was used to describe the compounds from minerals.
B. (2) The `18th` century chemists believed that nature possessed a certain vital force and that only living things could produce organic compounds.
C. (3) This romantic notion was disproved in `1828` by Friedrich Wohler, a German chemist, who synthesized urea (an organic compound) by boiling ammonium cyanide (an inorganic compound) with water.
D. (4) We encounter organic chemistry in every aspect of our lives. All life is based on a complex interrelationship of thousances.

Answer

C

Explanation

`F`. Wholer synthesized urea (a constituent of urine) by evaporating an aqueous solution containing ammonium cyanate `(NH_(4)OCN)`, a compound obtained from nonliving materials. He also prepared urea from the reaction between inorganic compounds, lead cyanate, and aqueous ammonia:
`Pb(OCN)_(2) + 2NH_(3) + 2H_(2)O rarr 2(NH_(2))_(2)CO + Pb(OH)_(2)`
(1) Although we still use the term organic, it no longer distinguishes between compounds of living and nonliving origin. Today we know that there are no fundamental difference between organic and iorganic compounds-the same principles apply to both of them.
(2) Today many organic compounds are manufactured from inorganic materials.
(4) The compounds of carbon are central to life on this planet. Carbon compounds include `DNA`, the giant helical molecules that contain all our genetic information. They include proteins that catalyze all of the reactions in our body, and that constitute the essential compounds of our blood, muscle, and skin. Together with oxygen, from the air we breath, carbon compounds furnish the energy that sustains life.
