CBSE - IX - Chemistry - Is Matter Around Us Pure?
How can we determine whether a compound is organic or inorganic ?
- Organic compounds contain carbon with the exception of few carbon compounds like oxides, carbonates, carbides and cyanides which are inorganic compounds.
- They generally do not dissolve in water but dissolve in organic solvents like alcohol, benzene and chloroform.
- They have low m.p andb.p and decompose easily on heating.
- They are inflammable and catch fire easily.
- They form covalent bonds and are non-electrolytes.
- Organic compounds have characteristic colour and odour and show the phenomenon of isomerism.
- Inorganic compounds do not contain carbon except for the following carbon compounds; oxides, carbonates, carbides and cyanides.
- They dissolve in water but insoluble in organic solvents.
- They have high m.p and b.p and usually do not decompose on heating.
- They do not burn easily and form ionic bonds.
- They are good electrolytes.
- They do not show the phenomenon of isomerism and most of them are colourless and odourless.
