The molecular formula of an alkyne is CnH2n-2.

Here's the step by step explanation:

1. Alkynes are hydrocarbons, which means they are composed of hydrogen (H) and carbon (C) atoms.

2. The general molecular formula for alkynes is CnH2n-2.

3. In this formula, 'n' represents the number of carbon atoms.

4. The '2n-2' part represents the number of hydrogen atoms, which is always double the number of carbon atoms minus 2.

5. For example, if an alkyne has 3 carbon atoms (n=3), it would have 2*3-2 = 4 hydrogen atoms. So, the molecular formula would be C3H4.
