p-Dibromobenzene has more than one C 2 axis. When two or more possible axes have the same order, preference is given to the axis passing through the greater number of atoms : the principal axis is the C 2 axis lying in the molecular plane and passing through the two Br-bearing carbons (C 1 and C 4 ), which contains four atoms (2 C + 2 Br). Ans. C 2 (the in-plane axis through C 1 and C 4 )
