Verified step by step guidance1
Understand that alkynes are hydrocarbons with at least one carbon-carbon triple bond. The general formula for alkynes is CnH2n-2.
Identify the number of carbon atoms in the alkyne. In this case, the problem specifies 4 carbon atoms.
Apply the general formula for alkynes: CnH2n-2. Substitute n with 4, which represents the number of carbon atoms.
Calculate the number of hydrogen atoms using the formula: H = 2n - 2. For n = 4, calculate 2(4) - 2.
Combine the number of carbon and hydrogen atoms to write the molecular formula for the alkyne: C4H6.
