Why wouldnt C2H2 (ethyne) be polar even if it had a divisible axis?

Thanks in advance (i think)

isn't because the charge is the same at both ends?

Ok I think that works. The hydrogen partial negatives would cancel. Thanks!

Because one of the species is not more electronegative than the other.

H-C(triple)C-H

Even though the CH bonds may be slightly polar, the polarity is canceled out on account of the molecule being symmetrical, because the polarity when added together comes to zero. Which it is.
