UNIT 1 : NATURE OF ORGANIC COMPOUNDS
1.why are organic reactions slow when compared to inorganic reactions?
Answer : Organic reactions are slow when compared to inorganic reactions because organic compounds contain strong covalent bonding making it harder for the molecules to react. As a result of this, organic reactions are slower.
2.(a) Mention the seven steps involved in investigating an organic compound.
(b). In what special situation is distillation under reduced pressure applied?(c). What is the basic difference between chromatography and other purification techniques known?
Answer : (a) Crystallisation, sublimation, simple distillation, fractional distillation, fractional Crystallisation, distillation under reduced pressure, steam distillation.
(b)i. It is used to purify a liquid which decomposes at a temperature below its boiling point in which case it cannot be distilled in the normal way, under atmospheric pressure.
Ii. It is also used when a solution in which the solute is capable of decomposing at the boiling point of the solvent is to be concentrated.
(c). Chromatography deals with the distribution of substances between two phases( which are stationary and mobile phases) while other purification methods can involve mixtures of the same phases.
