What are clathrates explain?
Clathrates are a class of chemical substance in which a molecule of a certain type is trapped within a cage or lattice formed from molecules of a second type; if the cage is formed from water molecules, the structure is known as a hydrate.
What are clathrates give example?
clathrate A compound in which molecules of one substance, commonly a noble gas, are completely enclosed within the crystal structure of another substance. Typical examples are Kr and Xe encapsulated in zeolite structures, or Ar, Kr, and Xe trapped in water ice.
What are clathrates general formula?
Hofmann compounds are coordination polymers with the formula Ni(CN)4·Ni(NH3)2. These materials crystallize with small aromatic guests (benzene, certain xylenes), and this selectivity has been exploited commercially for the separation of these hydrocarbons. Metal organic frameworks (MOFs) form clathrates.
What are the uses of clathrates?
Other applications of clathrate hydrates include the separation of gases such as CO2 from flue gases and desalination. Clathrate hydrates can be used in flue gases to separate CO2 by encouraging the formation of CO2 clathrate hydrate in a flue gas mixture.
Is used to make clathrate compound?
carbon dioxide—form crystalline hydrates called clathrate compounds at relatively low temperatures and pressures. Clathrate crystals have a structure in which the water molecules form a loosely held framework surrounding the gas molecule.
What is 4CH4?
Methane clathrate is a clathrate compound that is an ice-like solid that consists of methane which is trapped within the crystal structure of water. It has formula CH4. 5.75H2O or 4CH4. It contains a methane and a water.
Which molecule Cannot be entrapped in clathrates?
The formation of a host-guest inclusion is dependent upon the size of the cavity. The clathrates that are formed by the quinol molecules have large size and hence the small noble gas molecules of helium and neon cannot be contained within those cavities as the cavities are larger in comparison to their size.
Which interaction is responsible for clathrate compound?
Inclusion (Clathrate) Compounds A liquid clathrate is a member of a group of liquid inclusion compounds that form upon the interaction of aromatic molecules (guests) with certain species related geometrically to salts such as [NMe4][Al2(CH3)6I].
Why does a clathrate form?
CH4 clathrate (or CH4 hydrate) is an ice-like compound formed when water freezes in the presence of sufficient CH4 and other gases, such that these gases become trapped within the water molecule lattice.
Which can form clathrate compound?
The clathrates that are formed by the quinol molecules have large size and hence the small noble gas molecules of helium and neon cannot be contained within those cavities as the cavities are larger in comparison to their size. Hence, helium and neon do not form clathrate compounds with quinol.
How many hydrogen atoms are there in 4CH4?
Explanation: One mole of methane specifies NA , Avogadro’s number of methane molecules, i.e. 6.022×1023 individual CH4 molecules. And thus it contains 4×6.022×1023 hydrogen atoms .
