The molecule is a para-disubstituted benzene.

1. One para position: the ring carbon is bonded directly to a carbonyl carbon (C=O), and that carbonyl carbon is also bonded to a trifluoromethyl group (-CF3).

2. Opposite para position: the ring carbon is bonded to a methylsulfonyl group, i.e., sulfur double-bonded to two oxygens and single-bonded to methyl.
