  ORGANIC COMPOUNDS Modern definition. C ompounds of carbon, hydrogen and their derivatives, are called organic compounds. For example, CH 4  , CH 3 Cl etc. Contents Sources of organic Compounds:  Following are the main sources of organic compounds: i. Fossil fuels or Fossil remains.  ii. Plants and Natural product  iii. Partial &Total Synthesis iv.  Fermentation and Biotechnology Fossil fuels or Fossil remains:   The main sources of fossil fuels or fossil remains are:  a. coal b. petroleum c. gas a. Coal:  Coal is one of the organic compounds. Coal major source of into coke, and coal law" on pyrolysis Com can be converted destructive distillation. More than 200 organic compounds" have been directly isolated from coal tar, which are used. in ...drug. dyes, other. preparation of perfumes.. photographic developers and. b. Petroleum: Petroleum Sticky Liquid ground in that is block Thick seeps out of the s...

Question 1: What is functional group? Answer.  An atom or group of atoms, double bond or triple bond, whose presence in a molecule gives its characteristics physical and chemical properties is called functional group. Examples:-Cl, -Br, - I, OH, double bond, triple bond etc. Question 2: What is difference between partial and total synthesis of organic compound? Answer. Organic compounds can be synthesized by partial synthesis and total synthesis. Partial synthesis The process in which organic compounds can be synthesized from natural product (coal, gas, petroleum) or an intermediate product is called partial synthesis. For example, when a carboxylic acid is obtained from oxidation of aldehyde instead of alkane or alcohol. R-CHO  + [O] - - - - - - - - - > RCOOH Total synthesis The process in which organic compounds can be synthesized from a cheap and easily available product through several steps is called total synthesis of organic compounds. For example, when a ...
