Select ine factor which is incorrect about the difficulties in the analysis of enantiomers ik GC-MS

1. A minority if detectors can differentiate between enantiomees

2. Enantioners may have a similar fragmentation pattern and this will make it difficult to discriminate between them

3. Enantiomers will have a similar boiling point and therefore their retention times may be very similar

4. The analysis of enantiomers is not possible with GC-MS

( i dont think it is 3 because im pretty sure enantiomers have the same boiling point)
