 Does ethyne display any carbon-carbon rotation about the bond between the two carbon atoms?

    No. Only single bonds have free rotation, so ethane has carbon-carbon rotation, but ethyne with its triple bond cannot.

    This is also the reason why alkenes have cis and trans isomers: the carbons can't revolve around the double bond.
