Question
Consider the molecule chloroacetylene HCCCL, with a triple bond between the two carbon atoms. The dipole moment is arranged with the positive end of the molecule on the chloride side. Is this what you expect? How can you account for it? Would you expect the H to exchange with D in D2O? Would you expect C-Cl to hydrolyze in water?

Yes , it is correct the positive end of the molecule is on the chloride side .
Reason : The electroneagive character of Carbon is greater than Chlorine as carbon forms triple bond it is in sp hybridized state which increases its electronegativity and which is greater than chlorine . So carbon pulls electron density towards itself making it partially negative .
C-Cl doesnt undergo hydrolysis . example take CCl4
H and D can exchange each other in D2O or H2O
