Which of the following statements is not true?a)Intermolecular hydroge...
Explanation:
Intramolecular hydrogen bonds are formed within the same molecule, not between two different molecules of the same compound. Therefore, option B is not true.
Intermolecular Hydrogen Bonds:
- Intermolecular hydrogen bonds are formed between two different molecules of compounds.
- It occurs when a hydrogen atom is attracted to an electronegative atom (such as oxygen, nitrogen, or fluorine) in a different molecule.
- These bonds are relatively weaker compared to intramolecular hydrogen bonds.
- Intermolecular hydrogen bonds play a significant role in determining the physical properties of a compound, such as boiling point, melting point, and solubility.
Intramolecular Hydrogen Bonds:
- Intramolecular hydrogen bonds are formed within the same molecule.
- It occurs when a hydrogen atom is attracted to an electronegative atom within the same molecule.
- These bonds are relatively stronger than intermolecular hydrogen bonds.
- Intramolecular hydrogen bonds can have a strong influence on the structure, stability, and reactivity of a molecule.
Hydrogen Bonds and Physical Properties:
- Hydrogen bonds have a strong influence on the physical properties of a compound.
- The presence of hydrogen bonds can increase the boiling point and melting point of a compound.
- Hydrogen bonds also affect the solubility of a compound in polar solvents.
- Compounds with hydrogen bonds tend to have higher viscosity and surface tension.
- Hydrogen bonds can also affect the acidity and basicity of compounds.
- Overall, hydrogen bonds play a crucial role in determining the physical properties and behavior of many substances.
Conclusion:
- Option B is not true because intramolecular hydrogen bonds are formed within the same molecule, not between two different molecules of the same compound.
- Intermolecular hydrogen bonds are formed between different molecules of compounds.
- Hydrogen bonds have a strong influence on the physical properties of a compound.
