Identical side chains are indicated hy the multiplicative prefixes di, tri,
tetra, penta, etc. If side chains with identical further substituents are present the multiplicative prefix forms his, tris, tetrakis, pentakis, etc. are
employed. (The prefix forms hi, ter, quater, quinque, sexi, septi, etc. are
reserved for direct linking of identical units; see the following Sections.)

If such a complex hydrocarbon system is present as a substituent group,
the free valence must again be assigned locant 1; only then are the usual
prority rules applied accordingly.
