प्रश्न
Distinguish between Nitrogen base and a base found in inorganic chemistry.
उत्तर १
Nitrogen base | Base in inorganic chemistry |
An organic molecule containing Nitrogen and has some chemical properties of a base. | Inorganic base is a substance they are metal oxides or hydroxides. Base is also a substance that can donate pair of electrons to other elements to form new molecule. |
Nitrogen is an odourless, colourless & tasteless gas so reacts easily with other elements. | Characters of a base- Base is soapy or slimpy substance bitter in taste. |
This reactivity makes it an important part in compounds necessary for life | React with acid-precipitate to form salts |
