In the presence of one or more characteristic groups that may be expressed u sing one or
more suffixes (–NH 2 , – OH, –COOH, etc.), the name of the parent hydride carrying the
highest-ranking s uch group is modified by the suffix, a nd other substituents are then denoted
by prefixes as described in Section IR-6.3.1. If acting as a s ubstituent, the group 13–16
parent hydride name i n q uestion is modified by changing the ending ‘ane’ to ‘anyl’ (or ‘yl’
for the group 14 elements), ‘anediyl’, etc.

Examples:
14. (EtO) 3 GeCH 2 CH 2 COOMe
methyl 3-(triethoxygermyl)propanoate
15. H 2 As(CH 2 ) 4 SO 2 Cl
4-arsanylbutane-1-sulfonyl chloride

Sometimes it may be necessary or preferable to consider a p arent hydride i n w hich several
(four or more) skeletal carbon atoms of a h ydrocarbon have been replaced by main group
elements. In this method of skeletal replacement the heteroatoms are designated by the ‘a’
terms of replacement nomenclature (Table X ) c ited in the order given by Table VI and
preceded by the appropriate locant(s). The rules for locant numbering are specified in
Section IR-6.2.4.1 and this nomenclature is fully described in Sections P-21.2 and P-22.2
of Ref. 3.

When elements from groups 13–16 replace carbon atoms in monocyclic systems, the
resulting structures m ay be named using t he extended Hantzsch–Widman procedures. This
