On the other hand, if we talk about their physical attributes, alkynes have certain similarities with alkanes and alkenes, with the difference that in this case they are elements with higher polarity, said polarity is generated by the presence of carbon “sp” in electrons.
We must bear in mind that alkynes are more reactive , this means that when exposed to certain elements such as water, dust and others, they can oxidize more easily. Also, due to the bond between hydrogen and carbon, it has a greater tendency to ionize.
In contact with water they are poorly soluble or not at all, the opposite occurs when they are in contact with other inorganic compounds such as solvents such as ether, benzene and carbon tetrachloride.
30 Examples of Alkynes
- 3-ethyl -5-ethynylhepta-1,6-diino
- October 3
- Ethyl Acetylene
- Methyl acetylene
- Propyl Acetylene
- Terbutyl Acetylene
One of the simplest alkynes in terms of its composition is acetylene , there is also propylene and butyne, these compounds are gases, on the other hand, alkynes that have a higher concentration of carbon atoms turn out to be liquid or solid.
In summary we can conclude that these elements are of great use within industrial chemistry, they are used in other activities such as construction for their ability to weld materials, for example acetylene is a gas much less heavy than air and highly flammable due to which is even capable of melting metals such as steel since with proper and correct use it can reach quite high temperatures, other types of alkynes are used for the production of polymers and other products.
