Molecular Solids

The Solid is a most vital type of Matter. Also, solid is classified into two categories one is the crystalline solids, and it is also classified into four categories. The Crystalline solid types are ionic solids,  network covalent solids, molecular solids, and metallic solids. All are these most important and major types of solids. Apart from this, another solid is Amorphous solids. It is generally not most vital, and it’s not real. It’s too different from Crystalline solid. Also, Molecular Solids are solids that are made up of discrete molecules. The particles of this molecule are polar and non-polar molecular solid. Below is the short guide given about Molecular Solids. If you would like to know about it, then know here. 

Molecular Solids

Molecular solids are one type of Crystalline solid. It is pertinent to the London forces and intermolecular forces that are held between two chlorine molecules. It is relevant to the polar covalent bond. In various Crystalline solids types, it is one of the constituent particles of the Molecular solid that is packed up jointly. They are molecules of the substance. All these arranged molecules can be non–polar, which has the dipole moment = 0, etc., or they may be polar has dipole moment > 0, etc.

Moreover, it is made up of molecules and atoms, and it is made up together with van der Waals forces. Because of this dipole, London forces are then weaker from the iconic and covalent bond. Ordinarily, the molecular solids are essentially too smooth and have a moderately very low melting temperature. Apart from this, there are molecular solids classified into three types: non-polar molecular solids, Polar molecular solids, and Hydrogen-bonded molecular solids. For instance, HCl, F, O, N, etc. 

Definition of London Force

The London force is excessively too weak attractive forces among molecules and atoms. This force is essentially caused by electrostatic attraction. Moreover, the London forces are the most attractive forces that induce due to the nonpolar substances. It is caused due to reduction of freezing and liquids into solids. It is based upon the temperature being reduced adequately.

Types of Molecular Solids with properties 

You know very well that Molecular Solids are an essential type of Crystalline solids. Molecular Solids are further classified into three parts. Its types or constituents particles are polar, non-polar solid, and hydrogen-bonded. Below, you can know about its all types in-depth. 

(i) Polar Molecular solids

It is held with molecules and atoms by a polar covalent bond. Also, the atoms and molecules are communed by relatively more robust dipole interactions. Also, the properties of this are that the physical nature of the molecules is too smooth and which includes almost all liquids and gases, it is based upon the room temperature. The Polar Molecular solids have not conducted electricity, and it has a higher melting point as compared to the non-polar molecular solids. Examples of this are HCl, SO2, NH3, etc. So, that’s all about the first type of molecular solids, which is polar molecular solids. 

(ii) Non Molecular solids

Instead of the Polar Molecular solids, then another type of Molecular solids is non-molecular solids. The molecules are formed with Molecules and atoms. It’s relatively shared together with a nonpolar covalent bond. Apart from this, the atoms and molecules are basically held by too weak London forces and dispersion forces. The properties of the Non Molecular solids are that the physical nature of the Non Molecular solids is too soft as compared to polar molecular solids. Moreover, the Non Molecular solids are not able to conduct electricity. Hence they are known as an insulator. The melting point of the Non Molecular solids is too low compared to molecular types. An example of the Non Molecular solids are H2, Cl2, I2, etc.

(iii) Hydrogen Molecular Solids

Another type of Molecular solid is Hydrogen-Bonded Molecular Solids, which have included the polar covalent bonds with Oxygen, nitrogen, hydrogen, and other Fluorine atoms. The Hydrogen-Bonded Molecular Solids are maintained jointly by the most powerful hydrogen bonding. Apart from this, the property of the Hydrogen-Bonded Molecular Solids is that their physical nature is too hard as compared to its other types. The Hydrogen-Bonded Molecular Solids are not able to conduct electricity. Despite this, the physical state of the Hydrogen-Bonded Molecular Solids is exclusively too soft and volatile liquids solids as per or under the room temperature. Furthermore, the Hydrogen-Bonded Molecular Solids melting point is too low. Examples of the Hydrogen-Bonded Molecular Solids are ice or H2O. 

Thus, all are the types, and a short guide is given about the Molecular solids, which are the most vital type of Crystalline solids. 

Conclusion 

Thus, these are the following aforementioned points that explain the Molecular Solids. You know very well that it is a Crystalline solid. Its examples are Water ice, Halogen compounds with hydrogen (e.g., HCl), Solid carbon dioxide, Hydrocarbons, Yellow arsenic, Solid halogens, Sucrose, or table sugar, Fullerenes, Sulphur, Light chalcogens, White phosphorus, and Pnictogens, etc. All are the most vital examples that are made up of discrete molecules. The molecule constituents are London forces between two chlorine molecules. If you want to know about the Molecular Solids in detail, then you can follow the above-given information. Surely, the above-given information helps you to know every info about it and clears your doubts.
