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 |
