Which orbital is non directional?
They are non directional because they are spherical in shape and probability of finding electrons at a particular distance from the nucleus is same in all directions.
Define molecular solids. What is Hydrogen bond? Explain its type and also write its application
When the constituent particles of a solid are molecules, they are called molecular solids.
They are held together by either:
Hydrogen bond is the bond that exists between a hydrogen of a molecule (which is bonded with a strong electronegative atom) with another highly electronegative atom.
It may be between within a molecule, molecules of same species, or molecules of different species.
Types of hydrogen bonds are:
- Intermolecular Hydrogen Bond
It is the bond between different molecules of same or different species.
Eg: HF, H2O, ROH, H2O and NH3, etc.
- Intramolecular Hydrogen Bond
It is the bond between hydrogen and electronegative atom of the same molecule.
