Explanation
A mixture of calcium formate and calcium acetate on dry distillation gives aldehydes (i.e, acetaldehyde).
Ca(HCOO)2 + Ca(CH3COO)2 → 2CH3CHO +2CaCO3
Carbonyl compounds are constituents of drugs, fabrics, plastics and flavourings.
In 1828, the German chemist Friedrich Wohler obtained urea artificially by treating silver cyanate with ammonium chloride.
AgNCO+NH4Cl → (H2N)2CO+AgCl
This was the first time an organic compound was artificially synthesized from inorganic starting materials, without the involvement of living organisms
Carboxylic acid esters of low molecular weight are colorless, volatile liquids with pleasant odors, slightly soluble in water. Many are responsible for the fragrance and flavor of flowers and fruits; for example, isopentyl acetate is present in bananas, methyl salicylate in wintergreen, and ethyl butyrate in pineapples. These and other volatile esters with characteristic odors are used in synthetic flavors, perfumes, and cosmetics.
Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic ester naturally produced by many species of plants particularly wintergreens. It also produced synthetically, used as a fragrance in foods and beverages.
