Assume that cyclobutane itself has D4h symmetry and that substituting H by Cl changes no other structure parameters. b. So, a molecular point group consists of all those symmetry operations that leave a point in the molecule invariant and permute identical atoms. Metabolic clearance was high (4.6 L/min) in the +/+ group, intermediate (2.4 L/min) in the +/0 group, and close to zero in 0/0 individuals, while the exhalation clearance was similar in the three groups.
