When alkynes are hydrogenated completely, they produce compounds with the general molecular formula
Answer Details
When alkynes are completely hydrogenated, each triple bond (-C≡C-) is converted to a single bond (-C-C-) and adds two hydrogen atoms. Therefore, each alkyne molecule loses two hydrogen atoms and gains two carbon atoms. The general molecular formula of completely hydrogenated alkynes is C nH 2n+2. Thus, is the correct answer.
