Which of the following describes the relationship between enantiomers regarding their physical properties?

1. They react at identical rates with achiral reagents and other chiral molecules such as enzymes.
2. They possess different solubilities and boiling points, allowing separation by fractional distillation methods.
3. One enantiomer is invariably a solid at room temperature, while its mirror-image partner remains a liquid.
4. They have identical melting and boiling points but rotate plane-polarized light in opposite directions.
