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 |
2 Types-
|
Turn red litmus to blue. |
| Chemistry of nitrogenuous bases is key in the functioning of DNA (allows complementary base pairing) |
उत्तर २
- Nitrogenous Base:
- Nitrogenous bases are organic molecules containing the element nitrogen & act as a base in the chemical reaction.
- e.g. Adenine, Thymine
- Base:
- Bases are the substance that release hydroxide (OH– ) ions in an aqueous solution.
- e.g. NaOH and Ca(OH)2
