{Statement (1): Ethyne (acetylene) has a triple bond between the carbon atoms, which is indeed shorter than the double bond in ethene.
Statement (2): Both carbon atoms in ethyne are sp hybridized because of the triple bond.
Statement (3):Ethyne is linear due to the sp hybridization of the carbon atoms.
Statement (4):The carbon-carbon bond in ethyne is stronger than that in ethene because the triple bond in ethyne has more bonding interactions.
Thus, statement (4) is incorrect, and the correct answer is (4).
