IR-10.4.3 Central atoms f rom groups 13–16 only
If the possible c entral atoms are both or all from class (ii), then the compound is named
substitutively as described in Section IR-10.3.3 (and in more detail in Section IR-6.3).
The parent hydride is chosen o n t he basis of the following element order (‘4’ m eaning
‘chosen before’, cf. S ection P-41 of Ref. 3):
N 4 P 4 As 4 Sb 4 Bi 4 Si 4 Ge 4 Sn 4 Pb 4
B 4 Al 4 Ga 4 In 4 Tl 4 S 4 Se 4 Te 4 C
Thus, for a c ompound containing both arsenic and lead, the parent hydride would be
selected as AsH 3 , r ather than PbH 4 , t he lead atom then appearing in the name as a p refixed
substituent, often with its own substituent g roups.
