Question

What are the important stuff to study in one of the hardest chemistry chapters of class 10th
– carbon and its compounds
and periodic classification of a elements

Answer 1

-------

• Covalent bond (definition, properties and example)
• Carbon (atomic no.,valency)
• Versatile nature of carbon
(i) tetravalency
(ii)Catenation
• Organic compounds
• Covalent compounds
• Hydrocarbons. (definition, example, classification, properties)
• Chemical properties of carbon compounds.
• Homologous series.
• Steps of nomenclature
• word root of carbon atoms.
• Soaps and detergent.

Periodic classification of a elements
---------

• Dobereiner’s triads (example, characteristic, limitations)
• Newlands’ Law of Octaves (characteristics, limitations)
