What is the chemical formula of Alkynes?

${C}_{{n}} {H}_{2 {n}-1}$
${C}_{{n}} {H}_{2 {n}}$
${C}_{{n}} {H}_{2 {n}-2}$
${C}_{{n}} {H}_{2 {n}+1}$

Solution:

The alkynes comprise a series of carbon and hydrogen based compounds that contain at least one triple bond. This group of compounds is a homologous series with the general molecular formula of

{C}_{{n}} {H}_{2 {n}-2}

, where n equals any integer greater than one.
