Boiling Point

The temperature at which a liquid's vapor pressure equals the external pressure surrounding the liquid, causing it to change into vapor.

S-2-butanol

A specific enantiomer of 2-butanol characterized by its spatial arrangement of atoms, having the hydroxyl group positioned for a specific optical activity.

R-2-butanol

An optically active form of 2-butanol, where the "R" denotes the configuration of the molecule at its chiral center.

Final Answer :
A
Explanation :
The boiling point of enantiomers is identical when measured under the same conditions, therefore both R-2-butanol and S-2-butanol have the same boiling point of 99°C.
