Can you name some naked eye stars that will turn into black holes eventually?
These would be all of the bright stars that are either supergiants, or are on the Main Sequence with spectral types of late-B or O type. These will become Type II supernova. I have not included binary stars with white dwarf companions that could become Type I supernova. I know of none that coincide with bright naked-eye stars other than Sirius, and Sirius B is too far from Sirius A to yield a supernova.
Here is a short list of the bright stars that satisfy will become Type II supernovae someday:
Polaris.......F8 Ib Rigel.........B8 Ia Arneb.........F0 Ib Alnilan.......B0 Ia Alnitak.......O9 Ib Saiph.........B0 I Betelgeuse....M2 I Canopus.......F0 Ib Wezen.........F8 Ia Aludra........B5 Ia Antares.......M1 Ib Deneb.........A2 Ia
