Hint: A lower pH indicates that the solution is more acidic, resulting in a higher concentration of positive hydrogen ions in the solution. Acidic chemicals or compounds are those that have the property of an acid.
Complete answer:
An alkyne is an unsaturated hydrocarbon with at least one carbon—carbon triple bond in organic chemistry. A homologous sequence is formed by the simplest acyclic alkynes, which have only one triple bond and no other functional groups.
Alkanes are organic compounds that are completely made up of single-bonded carbon and hydrogen atoms with no other functional groups.
Alkenes are unsaturated hydrocarbons with at least one carbon-to-carbon double bond (e.g., containing only carbon and hydrogen). Olefins are a term used to classify alkenes. Because of the double bond, alkenes are more reactive than alkanes.
The tendency of an atom to attract shared electrons (or electron density) to itself is known as electronegativity. The electronegativity of an atom is determined by its atomic number as well as the distance between its valence electrons and the charged nucleus.
The alkynes are more electronegative due to the presence of more character. Hydrogen atoms can therefore be liberated as protons more readily in Ethyne. Hence, alkynes are more acidic than alkanes and alkenes.
Note:
The most commonly used alkyne in industry is acetylene, which is used as a fuel and a precursor to other compounds such as acrylates. The partial oxidation of natural gas produces hundreds of millions of kilogrammes per year. Thermal cracking of hydrocarbons produces propyne, which is also useful in industry.
