ecine Ending of parent names of ten-membered heteromonocycles with the maximum number of
non-cumulative double bonds in Hantzsch–Widman nomenclature, cf. S ection IR-6.2.4.3.
ene Ending of systematic names of acyclic and cyclic parent structures with double-bond
unsaturation, replacing ‘ane’ in the name of the corresponding saturated parent hydride,
and if necessary accompanied by locants and multiplicative prefixes specifying the
locations and number of double bonds, e.g. diazene, triazene, pentasil-1-ene, cyclopenta-
1,3-diene. Cf. S ections IR-6.2.2.3 and IR- 6.2.2.4.
Ending of certain acceptable non-systematic names of unsaturated cyclic parent hydrides,
e.g. benzene, azulene.
See also ‘irene’, ‘ocene’.
enide Combined ending of names of anions resulting from the removal of a h ydron from a p arent

hydride with an ‘ene’ name, formed by adding the suffix ‘ide’, e.g. diazenide, HN¼N .
Cf. S ection IR-6.4.4.
enium Combined ending of names of cations resulting from the addition of a h ydron to a p arent
structure with an ‘ene’ name, formed by adding the suffix ‘ium’, e.g. diazenium. Cf.
Section IR-6.4.1.
Combined ending resulting from the addition of the suffix ‘ium’ to a m etallocene name.
This leads to ambiguous names, see Section IR-10.2.6.

eno Ending resulting from the change of the ‘ene’ ending in names of cyclic mancude ring
systems to ‘eno’ to form prefixes in fusion nomenclature. (See Section P-25.3 of the Blue
b
Book .)
Ending resulting from the change of the ‘ene’ ending in names of parent hydrides to form
prefixes denoting bridging divalent substituent groups, e.g. diazeno, N¼N .
epane Ending of parent names of seven-membered saturated heteromonocycles in Hantzsch–
Widman nomenclature, cf. S ection IR-6.2.4.3.
epine Ending of parent names of seven-membered heteromonocycles with the maximum number
of non-cumulative double bonds in Hantzsch–Widman nomenclature, cf. S ection IR-
6.2.4.3.
etane General ending of parent names of four-membered saturated heteromonocycles in
Hantzsch–Widman nomenclature, cf. S ection IR-6.2.4.3. See also ‘etidine’.
ete Ending of parent names of four-membered heteromonocycles with the maximum number
of non-cumulative double bonds in Hantzsch–Widman nomenclature, cf. S ection IR-
6.2.4.3.

etidine Ending of parent names of four-membered nitrogen-containing saturated
heteromonocycles in Hantzsch–Widman nomenclature, cf. S ection IR-6.2.4.3.
ic Ending of names of many acids, both inorganic and organic, e.g. sulfuric acid, acetic acid,
benzoic acid. For more examples, particularly of inorganic ‘ic’ acid names, see Tables
IR-8.1 and IR-8.2, and Table IX. See also ‘inic’ and ‘onic’.
Ending formerly added to stems of element names to indicate a h igher oxidation state, e.g.
ferric chloride, cupric oxide, ceric sulfate. Such names are no longer acceptable.
ide Ending of names of monoatomic and homopolyatomic anions, e.g. chloride, sulfide,
disulfide(2 ), triiodide(1 ). Cf. S ections IR-5.3.3.2 and IR-5.3.3.3 and Table IX.
Ending of names of formally electronegative homoatomic constituents in compositional
names, e.g. disulfur dichloride. Cf. S ection IR-5.4.
