BondChiralCount [BCC, BCCNT]: Total count of chiral bonds in a given compound, integer.
BondChiralDefCount [BCDC, BCDCNT]: Total count of defined chiral bonds in a given compound, integer.
BondChiralUndefCount [BCUC, BCUCNT]: Total count of undefined
chiral bonds in a given compound, integer.

I am confused on what is a chiral bond. I thought enantiomers (chiral molecules) had chiral atoms, not bonds. Are cis/trans isomers chiral bonds? If so, the boiling points are different, and enatiomers have the same boiling points, right? So what is a chiral bond?
