When mono substituted benzene is subjected to further substitution, di-substituted products are formed. They are Ortho, para and meta. The product which is formed more predominately depends on nature of the substituents already present in the benzene ring. This is known as direct influence of substituents. Ortho and para directing groups: They direct the incoming Read more about Directive influence of functional groups in mono substituted benzene[…]

Acyclic or open chained compounds: Also called aliphatic compounds. Consist of straight or branched compounds. Alicyclic or closed chained compounds: Also called aliphatic cyclic. Carbon atoms are bonded in the form of a ring. Homocyclic – consisting only of carbon atoms joined in the ring. Heterocyclic – consist of atoms other than carbon joined in Read more about Classification of organic compounds[…]

Alkynes: These are unsaturated hydrocarbons containing at least one triple bond between two carbons. General formula is Cn H2n-2,               (n = 2, 3, 4, 5, …). Acetylene is first member Nomenclature and isomerism: The IUPAC name is derived from the IUPAC name of alkanes by replacing ending ‘ane’ by ‘yne’ along with the position of Read more about Alkynes – Nomenclature and isomerism, Structure of acetylene[…]

Quantitative analysis is the determination of the absolute or relative abundance (often expressed as a concentration) of one, several or all particular substance(s) present in a sample. 1. Carbon and Hydrogen: Liebig’s combustion method: A known weight of organic compound is heated with pure and dry cupric oxide in a steam of pure and dry oxygen, Read more about Quantitative Analysis[…]

• Acid rains occur due to presence of oxides of nitrogen & Sulphur in rain water. • Nitric acid & sulphuric acid in the atmosphere dissolve in rain water and come down to earth as acid rain. • The rain water which contains nitric acid and sulphuric acid is called acid rain. • Acid rain Read more about Acid rains[…]
